In __set_free we will check whether all segment are free in one section when free one segment, in order to set section to free status. But the searching region of segmap is from start segno to last segno of main area, it's not necessary. So let's just only check all segment bitmap of target section. Signed-off-by:

This patch doesn't make any effect on previous behavior, since f2fs_write_data_page bypasses writing the page during POR. But, the difference is that this patch avoids holding writepages mutex. This is to avoid the following false warning, since this can happen only when mount and shutdown are triggered at the same time. ====================================================== [ INFO: possible circular locking dependency detected ] 4.0.0-rc1+ #3 Tainted: G O ------------------------------------------------------- kworker/u8:0/2270 is trying to acquire lock: (&sbi->gc_mutex){+.+.+.}, at: [<ffffffffa02bdd33>] f2fs_balance_fs+0x73/0x90 [f2fs] but task is already holding lock: (&sbi->writepages){+.+...}, at: [<ffffffffa02b261b>] f2fs_write_data_pages+0xcb/0x3a0 [f2fs] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #2 (&sbi->writepages){+.+...}: [<ffffffff810e2b11>] lock_acquire+0xe1/0x2f0 [<ffffffff8185e1b3>] mutex_lock_nested+0x63/0x530 [<ffffffffa02b261b>] f2fs_write_data_pages+0xcb/0x3a0 [f2fs] [<ffffffff811c38c1>] do_writepages+0x21/0x50 [<ffffffff8126c5a6>] __writeback_single_inode+0x76/0xbf0 [<ffffffff8126e23a>] writeback_single_inode+0xea/0x1c0 [<ffffffff8126e425>] write_inode_now+0x95/0xa0 [<ffffffff81259dab>] iput+0x20b/0x3f0 [<ffffffffa02c1c8b>] recover_data.constprop.14+0x26b/0xa80 [f2fs] [<ffffffffa02c2776>] recover_fsync_data+0x2b6/0x5e0 [f2fs] [<ffffffffa02a9744>] f2fs_fill_super+0xb24/0xb90 [f2fs] [<ffffffff8123d7f4>] mount_bdev+0x1a4/0x1e0 [<ffffffffa02a3c85>] f2fs_mount+0x15/0x20 [f2fs] [<ffffffff8123e159>] mount_fs+0x39/0x180 [<ffffffff8125e51b>] vfs_kern_mount+0x6b/0x160 [<ffffffff81261554>] do_mount+0x204/0xbe0 [<ffffffff8126223b>] SyS_mount+0x8b/0xe0 [<ffffffff81863e6d>] system_call_fastpath+0x16/0x1b -> #1 (&sbi->cp_mutex){+.+...}: [<ffffffff810e2b11>] lock_acquire+0xe1/0x2f0 [<ffffffff8185e1b3>] mutex_lock_nested+0x63/0x530 [<ffffffffa02acbf2>] write_checkpoint+0x42/0x1230 [f2fs] [<ffffffffa02a847d>] f2fs_sync_fs+0x9d/0x2a0 [f2fs] [<ffffffff81272f82>] sync_filesystem+0x82/0xb0 [<ffffffff8123c214>] generic_shutdown_super+0x34/0x100 [<ffffffff8123c5f7>] kill_block_super+0x27/0x70 [<ffffffffa02a3c60>] kill_f2fs_super+0x20/0x30 [f2fs] [<ffffffff8123ca49>] deactivate_locked_super+0x49/0x80 [<ffffffff8123d05e>] deactivate_super+0x4e/0x70 [<ffffffff8125df63>] cleanup_mnt+0x43/0x90 [<ffffffff8125e002>] __cleanup_mnt+0x12/0x20 [<ffffffff810a82e4>] task_work_run+0xc4/0xf0 [<ffffffff8101f0bd>] do_notify_resume+0x8d/0xa0 [<ffffffff81864141>] int_signal+0x12/0x17 -> #0 (&sbi->gc_mutex){+.+.+.}: [<ffffffff810e2866>] __lock_acquire+0x1ac6/0x1c90 [<ffffffff810e2b11>] lock_acquire+0xe1/0x2f0 [<ffffffff8185e1b3>] mutex_lock_nested+0x63/0x530 [<ffffffffa02bdd33>] f2fs_balance_fs+0x73/0x90 [f2fs] [<ffffffffa02b5938>] f2fs_write_data_page+0x348/0x5b0 [f2fs] [<ffffffffa02af9da>] __f2fs_writepage+0x1a/0x50 [f2fs] [<ffffffff811c1b54>] write_cache_pages+0x274/0x6f0 [<ffffffffa02b2630>] f2fs_write_data_pages+0xe0/0x3a0 [f2fs] [<ffffffff811c38c1>] do_writepages+0x21/0x50 [<ffffffff8126c5a6>] __writeback_single_inode+0x76/0xbf0 [<ffffffff8126d44a>] writeback_sb_inodes+0x32a/0x710 [<ffffffff8126d8cf>] __writeback_inodes_wb+0x9f/0xd0 [<ffffffff8126dcdb>] wb_writeback+0x3db/0x850 [<ffffffff8126e848>] bdi_writeback_workfn+0x148/0x980 [<ffffffff810a3782>] process_one_work+0x1e2/0x840 [<ffffffff810a3f01>] worker_thread+0x121/0x460 [<ffffffff810a9dc8>] kthread+0xf8/0x110 [<ffffffff81863dbc>] ret_from_fork+0x7c/0xb0 Signed-off-by: -

Now in f2fs, we share functions and structures for batch mode and real-time mode discard. For real-time mode discard, in shared function add_discard_addrs, we will use uninitialized trim_minlen in struct cp_control to compare with length of contiguous free blocks to decide whether skipping discard fragmented freespace or not, this makes us ignore small discard sometimes. Fix it. Signed-off-by:

cp_payload is introduced for sit bitmap to support large volume, and it is just after the block of f2fs_checkpoint + nat bitmap, so the first segment should include F2FS_CP_PACKS + NR_CURSEG_TYPE + cp_payload + orphan blocks. However, current max orphan inodes calculation don't consider cp_payload, this patch fix it by reducing the number of cp_payload from total blocks of the first segment when calculate max orphan inodes.

block operations is used to flush all dirty node and dentry blocks in the page cache and suspend ordinary writing activities, however, there are some facts such like cp error or mount read-only etc which lead to block operations can't be invoked.

This patch introduces a generic ioctl for fs shutdown, which was used by xfs. If this shutdown is triggered, filesystem stops any further IOs according to the following options. 1. FS_GOING_DOWN_FULLSYNC : this will flush all the data and dentry blocks, and do checkpoint before shutdown. 2. FS_GOING_DOWN_METASYNC : this will do checkpoint before shutdown. 3. FS_GOING_DOWN_NOSYNC : this will trigger shutdown as is. Signed-off-by:

This patch adds a fast lookup path for rb-tree extent cache. In this patch we add a recently accessed extent node pointer 'cached_en' in extent tree. In lookup path of extent cache, we will firstly lookup the last accessed extent node which cached_en points, if we do not hit in this node, we will try to lookup extent node in rb-tree. By this way we can avoid unnecessary slow lookup in rb-tree sometimes. Note that, side-effect of this patch is that we will increase memory cost, because we will store a pointer variable in each struct extent tree additionally. Signed-off-by:

This patch enables rb-tree based extent cache in f2fs. When we mount with "-o extent_cache", f2fs will try to add recently accessed page-block mappings into rb-tree based extent cache as much as possible, instead of original one extent info cache. By this way, f2fs can support more effective cache between dnode page cache and disk. It will supply high hit ratio in the cache with fewer memory when dnode page cache are reclaimed in environment of low memory.

This is a tricky story of the new atomic state handling and the legacy code fighting over each another. The bug at hand is an underrun of the framebuffer reference with subsequent hilarity caused by the load detect code. Which is peculiar since the the exact same code works fine as the implementation of the legacy setcrtc ioctl. Let's look at the ingredients: - Currently our code is a crazy mix of legacy modeset interfaces to set the parameters and half-baked atomic state tracking underneath. While this transition is going we're using the transitional plane helpers to update the atomic side (drm_plane_helper_disable/update and friends), i.e. plane->state->fb. Since the state structure owns the fb those functions take care of that themselves. The legacy state (specifically crtc->primary->fb) is still managed by the old code (and mostly by the drm core), with the fb reference counting done by callers (core drm for the ioctl or the i915 load detect code). The relevant commit is commit ea2c67bb Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Dec 23 10:41:52 2014 -0800 drm/i915: Move to atomic plane helpers (v9) - drm_plane_helper_disable has special code to handle multiple calls in a row - it checks plane->crtc == NULL and bails out. This is to match the proper atomic implementation which needs the crtc to get at the implied locking context atomic updates always need. See commit acf24a39 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Jul 29 15:33:05 2014 +0200 drm/plane-helper: transitional atomic plane helpers - The universal plane code split out the implicit primary plane from the CRTC into it's own full-blown drm_plane object. As part of that the setcrtc ioctl (which updated both the crtc mode and primary plane) learned to set crtc->primary->crtc on modeset to make sure the plane->crtc assignments statate up to date in commit e13161af Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) Unfortunately we've forgotten to update the load detect code. Which wasn't a problem since the load detect modeset is temporary and always undone before we drop the locks. - Finally there is a organically grown history (i.e. don't ask) around who sets the legacy plane->fb for the various driver entry points. Originally updating that was the drivers duty, but for almost all places we've moved that (plus updating the refcounts) into the core. Again the exception is the load detect code. Taking all together the following happens: - The load detect code doesn't set crtc->primary->crtc. This is only really an issue on crtcs never before used or when userspace explicitly disabled the primary plane. - The plane helper glue code short-circuits because of that and leaves a non-NULL fb behind in plane->state->fb and plane->fb. The state fb isn't a real problem (it's properly refcounted on its own), it's just the canary. - Load detect code drops the reference for that fb, but doesn't set plane->fb = NULL. This is ok since it's still living in that old world where drivers had to clear the pointer but the core/callers handled the refcounting. - On the next modeset the drm core notices plane->fb and takes care of refcounting it properly by doing another unref. This drops the refcount to zero, leaving state->plane now pointing at freed memory. - intel_plane_duplicate_state still assume it owns a reference to that very state->fb and bad things start to happen. Fix this all by applying the same duct-tape as for the legacy setcrtc ioctl code and set crtc->primary->crtc properly.
