The function ext4_calc_metadata_amount() has side effects, although it's not obvious from its function name. So if we fail to claim space, regardless of whether we retry to claim the space again, or return an error, we need to undo these side effects. Otherwise we can end up incorrectly calculating the number of metadata blocks needed for the operation, which was responsible for an xfstests failure for test #271 when using an ext2 file system with delalloc enabled.

If we hit a condition where we have allocated metadata blocks that were not appropriately reserved, we risk underflow of ei->i_reserved_meta_blocks. In turn, this can throw sbi->s_dirtyclusters_counter significantly out of whack and undermine the nondelalloc fallback logic in ext4_nonda_switch(). Warn if this occurs and set i_allocated_meta_blocks to avoid this problem. This condition is reproduced by xfstests 270 against ext2 with delalloc enabled: Mar 28 08:58:02 localhost kernel: [ 171.526344] EXT4-fs (loop1): delayed block allocation failed for inode 14 at logical offset 64486 with max blocks 64 with error -28 Mar 28 08:58:02 localhost kernel: [ 171.526346] EXT4-fs (loop1): This should not happen!! Data will be lost 270 ultimately fails with an inconsistent filesystem and requires an fsck to repair. The cause of the error is an underflow in ext4_da_update_reserve_space() due to an unreserved meta block allocation. Signed-off-by:

Whether to continue removing extents or not is decided by the return value of function ext4_ext_more_to_rm() which checks 2 conditions: a) if there are no more indexes to process. b) if the number of entries are decreased in the header of "depth -1". In case of hole punch, if the last block to be removed is not part of the last extent index than this index will not be deleted, hence the number of valid entries in the extent header of "depth - 1" will remain as it is and ext4_ext_more_to_rm will return 0 although the required blocks are not yet removed. This patch fixes the above mentioned problem as instead of removing the extents from the end of file, it starts removing the blocks from the particular extent from which removing blocks is actually required and continue backward until done.

This patch changes the 'ext4_handle_dirty_super()' function which submits the superblock for I/O in the following cases: 1. When creating the first large file on a file system without EXT4_FEATURE_RO_COMPAT_LARGE_FILE feature. 2. When re-sizing the file-system. 3. When creating an xattr on a file-system without the EXT4_FEATURE_COMPAT_EXT_ATTR feature. If the file-system has journal enabled, the superblock is written via the journal. We do not modify this path. If the file-system has no journal, this function, falls back to just marking the superblock as dirty using the 's_dirt' superblock flag. This means that it delays the actual superblock I/O submission by 5 seconds (default setting). Namely, the 'sync_supers()' kernel thread will call 'ext4_write_super()' later and will actually submit the superblock for I/O. And this is the behavior this patch modifies: we stop using 's_dirt' and just mark the superblock buffer as dirty right away. Indeed, all 3 cases above are extremely rare and it does not add any value to delay the I/O submission for them. Note: 'ext4_handle_dirty_super()' executes '__ext4_handle_dirty_super()' with 'now = 0'. This patch basically makes the 'now' argument unneeded and it will be deleted in one of the next patches. This patch also removes 's_dirt' condition on the unmount path because we never set it anymore, so we should not test it. Tested using xfstests for both journalled and non-journalled ext4.

Commit a0375156 properly notes that superblock doesn't need to be marked as dirty when only number of free inodes / blocks / number of directories changes since that is recomputed on each mount anyway.

This patch adds support for quotas as a first class feature in ext4; which is to say, the quota files are stored in hidden inodes as file system metadata, instead of as separate files visible in the file system directory hierarchy. It is based on the proposal at: https://ext4.wiki.kernel.org/index.php/Design_For_1st_Class_Quota_in_Ext4 This patch introduces a new feature - EXT4_FEATURE_RO_COMPAT_QUOTA which, when turned on, enables quota accounting at mount time iteself. Also, the quota inodes are stored in two additional superblock fields. Some changes introduced by this patch that should be pointed out are: 1) Two new ext4-superblock fields - s_usr_quota_inum and s_grp_quota_inum for storing the quota inodes in use. 2) Default quota inodes are: inode#3 for tracking userquota and inode#4 for tracking group quota. The superblock fields can be set to use other inodes as well. 3) If the QUOTA feature and corresponding quota inodes are set in superblock, the quota usage tracking is turned on at mount time. On 'quotaon' ioctl, the quota limits enforcement is turned on. 'quotaoff' ioctl turns off only the limits enforcement in this case. 4) When QUOTA feature is in use, the quota mount options 'quota', 'usrquota', 'grpquota' are ignored by the kernel. 5) mke2fs or tune2fs can be used to set the QUOTA feature and initialize quota inodes. The default reserved inodes will not be visible to user as regular files. 6) The quota-tools will need to be modified to support hidden quota files on ext4. E2fsprogs will also include support for creating and fixing quota files. 7) Support is only for the new V2 quota file format. Tested-by:

Aligned and overwrite direct I/O can be parallelized. In ext4_file_dio_write, we first check whether these conditions are satisfied or not. If so, we take i_data_sem and release i_mutex lock directly. Meanwhile iocb->private is set to indicate that this is a dio overwrite, and it will be handled in ext4_ext_direct_IO.

EXT4_GET_BLOCKS_NO_LOCK flag is added to indicate that we don't need to acquire i_data_sem lock in ext4_map_blocks. Meanwhile, it changes ext4_get_block() to not start a new journal because when we do a overwrite dio, there is no any metadata that needs to be modified. We define a new function called ext4_get_block_write_nolock, which is used in dio overwrite nolock. In this function, it doesn't try to acquire i_data_sem lock and doesn't start a new journal as it does a lookup.

In xattr block operation, we use h_refcount to indicate whether the xattr block is shared among many inodes. And xattr block csum uses s_csum_seed if it is shared and i_csum_seed if it belongs to one inode. But this has a problem. So consider the block is shared first bewteen inode A and B, and B has some xattr update and CoW the xattr block. When it updates the *old* xattr block(because of the h_refcount change) and calls ext4_xattr_release_block, we has no idea that inode A is the real owner of the *old* xattr block and we can't use the i_csum_seed of inode A either in xattr block csum calculation. And I don't think we have an easy way to find inode A. So this patch just removes the tricky i_csum_seed and we now uses s_csum_seed every time for the xattr block csum. The corresponding patch for the e2fsprogs will be sent in another patch. This is spotted by xfstests 117. Signed-off-by:

In ext4_rename, when the old name is a dir, we need to change ".." to its new parent and journal the change, so with metadata_csum enabled, we have to re-calc the csum. As the first block of the dir can be either a htree root or a normal directory block and we have different csum calculation for these 2 types, we have to choose the right one in ext4_rename. btw, it is found by xfstests 013.

Commit f975d6bc introduced bug which caused ext4_statfs() to miscalculate the number of file system overhead blocks. This causes the f_blocks field in the statfs structure to be larger than it should be. This would in turn cause the "df" output to show the number of data blocks in the file system and the number of data blocks used to be larger than they should be. Signed-off-by:

Currently ext4_mb_load_buddy is called for every group, irrespective of whether the group info is already in memory, while reading /proc/fs/ext4/<partition>/mb_groups proc file. For the purpose of mb_groups proc file, it is unnecessary to load the file group info from disk if it was loaded in past. These calls to ext4_mb_load_buddy make reading the mb_groups proc file expensive. Also, the locks around ext4_get_group_info are not required. This patch modifies the code to call ext4_mb_load_buddy only if the group info had never been loaded into memory in past. It also removes the mb group locking around ext4_get_group_info call.

The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu().
