Both btrfs_find_device() and find_device() does the same thing except that the latter does not take the seed device onto account in the device scanning context. We can merge them. Signed-off-by:

Preparatory patch to add ioctl that allows to forget a device (ie. reverse of scan). Refactors btrfs_free_stale_devices() to obtain return status. As this function can fail if it can't find the given path (returns -ENOENT) or trying to delete a mounted device (returns -EBUSY). Signed-off-by:

btrfs_find_device() accepts fs_info as an argument and retrieves fs_devices from fs_info. Instead use fs_devices, so that this function can be used in non-mount (during device scanning) context as well. Signed-off-by:

btrfs_find_device_by_devspec() finds the device by @devid or by @device_path. This patch makes code flow easy to read by open coding the else part and renames devpath to device_path. Signed-off-by:

Anand Jain authored
btrfs_find_device_missing_or_by_path() is relatively small function, and its only parent btrfs_find_device_by_devspec() is small as well. Besides there are a number of find_device functions. Merge btrfs_find_device_missing_or_by_path() into its parent. Signed-off-by:

In order to avoid duplicating init code for em there is an additional label, not_found_em, which is used to only set ->block_start. The only case when it will be used is if the extent we are adding overlaps with an existing extent. Make that case more obvious by: 1. Adding a comment hinting at what's going on 2. Assigning EXTENT_MAP_HOLE and directly going to insert. No functional changes. Reviewed-by:

Core btree functions in btrfs generally return 0 when an item is found, 1 in case the sought item cannot be found and <0 when an error happens. Consolidate the checks for those conditions in one 'if () {} else if () {}' construct rather than 2 separate 'if () {}' statements. This emphasizes that the handling code pertains to a single function. No functional changes. Reviewed-by:Qu Wenruo <wqu@suse.com> Reviewed-by:

found_type really holds the type of extent and is guaranteed to to have a value between [0, 2]. The only time it can contain anything different is if btrfs_lookup_file_extent returned a positive value and the previous item is different than an extent. Avoid this situation by simply checking found_key.type rather than assigning the item type to found_type intermittently. Also make the variable an u8 to reduce stack usage. No functional changes.

Move the check that verifies if both inodes have checksums disabled or both have them enabled, from the clone and deduplication functions into the new common helper btrfs_remap_file_range_prep(). Signed-off-by:

Nikolay Borisov authored
We can never have extents marked as EXTENT_MAP_DELALLOC since this value is only ever used by btrfs_get_extent_fiemap. In this case the extent map is created by btrfs_get_extent_fiemap and is never really published, this flag is used to return the corresponding userspace one. Considering this, it's pointless having a check for EXTENT_MAP_DELALLOC in mergable_maps. Just remove it. Signed-off-by:

ihold is supposed to be used when the caller already has a reference to the inode. In the case of cow_file_range_async this invariants holds, since the 3 call chains leading to this function all take a reference: btrfs_writepage <--- does igrab extent_write_full_page __extent_writepage writepage_delalloc btrfs_run_delalloc_range cow_file_range_async extent_write_cache_pages <--- does igrab __extent_writepage (same callchain as above) and submit_compressed_extents <-- already called from async CoW submit path, which would have done ihold. extent_write_locked_range __extent_writepage Signed-off-by: -

Nikolay Borisov authored
Make btrfs_get_extent_fiemap a bit more friendly. First step is to rename the closely related, yet arbitrary named range_start/found_end/found variables. They define the delalloc range that is found in case a real extent wasn't found. Subsequently remove an unnecessary check for hole_em since it's guaranteed to be set i.e the check is always true. Top it off by giving all comments a refresh. No functional changes. Signed-off-by:

Nikolay Borisov authored
This function is a simple wrapper over btrfs_get_extent that returns either: a) A real extent in the passed range or b) Adjusted extent based on whether delalloc bytes are found backing up a hole. To support these semantics it doesn't need the page/pg_offset/create arguments which are passed to btrfs_get_extent in case an extent is to be created. So simplify the function by removing the unused arguments. No functional changes. Reviewed-by:

This fixes a regression introduced by commit 0d2e778e "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

syzbot was able to trigger another soft lockup [1] I first thought it was the O(N^2) issue I mentioned in my prior fix (f657d22ee1f "net/x25: do not hold the cpu too long in x25_new_lci()"), but I eventually found that x25_bind() was not checking SOCK_ZAPPED state under socket lock protection. This means that multiple threads can end up calling x25_insert_socket() for the same socket, and corrupt x25_list [1] watchdog: BUG: soft lockup - CPU#0 stuck for 123s!
