2025-01-13btrfs: zoned: reclaim unused zone by zone resettingNaohiro Aota
On the zoned mode, once used and freed region is still not reusable after the freeing. The underlying zone needs to be reset before reusing. Btrfs resets a zone when it removes a block group, and then new block group is allocated on the zones to reuse the zones. But, it is sometime too late to catch up with a write side. This commit introduces a new space-info reclaim method ZONE_RESET. That will pick a block group from the unused list and reset its zone to reuse the zone_unusable space. It is faster than removing the block group and re-creating a new block group on the same zones. For the first implementation, the ZONE_RESET is only applied to a block group whose region is fully zone_unusable. Reclaiming partial zone_unusable block group could be implemented later.

2025-01-13btrfs: drop fs_info argument from btrfs_update_space_info_*()Naohiro Aota
Since commit e1e577aafe41 ("btrfs: store fs_info in space_info"), we have the fs_info in a space_info. So, we can drop fs_info argument from btrfs_update_space_info_*. There is no behavior change.

2025-01-13btrfs: factor out btrfs_return_free_space()Naohiro Aota
Factor out a part of unpin_extent_range() that returns space back to the space info, prioritizing global block reserve. Also, move the "len" variable into the loop to clarify we don't need to carry it beyond an iteration.

2025-01-13btrfs: handle FS_IOC_READ_VERITY_METADATA ioctlAllison Karlitskaya
Commit 146054090b08 ("btrfs: initial fsverity support") introduced fs-verity support for btrfs, but didn't add support for FS_IOC_READ_VERITY_METADATA to directly query the Merkle tree, descriptor and signature blocks for fs-verity enabled files. Add the (trival) implementation: we just need to wire it through to the fs-verity code, the same way as is done in the other two filesystems which support this ioctl (ext4, f2fs). The fs-verity code already has access to the required data. This is also safe to backport to older stable trees (5.15+) if needed.

2025-01-13btrfs: send: remove redundant assignments to variable retColin Ian King
The variable ret is being initialized to zero and also later re-assigned to zero. In both cases the assignment is redundant since the value is never read after the assignment and hence they can be removed.

2025-01-13btrfs: use PTR_ERR() instead of PTR_ERR_OR_ZERO() for btrfs_get_extent()Qu Wenruo
The function btrfs_get_extent() will only return an PTR_ERR() or a valid extent map pointer. It will not return NULL. Thus the usage of PTR_ERR_OR_ZERO() inside submit_one_sector() is not needed, use plain PTR_ERR() instead, and that is the only usage of PTR_ERR_OR_ZERO() after btrfs_get_extent().

2025-01-13btrfs: selftests: add delayed ref self test casesJosef Bacik
The recent fix for a stupid mistake I made uncovered the fact that we don't have adequate testing in the delayed refs code, as it took a pretty extensive and long running stress test to uncover something that a unit test would have uncovered right away. Fix this by adding a delayed refs self test suite. This will validate that the btrfs_ref transformation does the correct thing, that we do the correct thing when merging delayed refs, and that we get the delayed refs in the order that we expect. These are all crucial to how the delayed refs operate. I introduced various bugs (including the original bug) into the delayed refs code to validate that these tests caught all of the shenanigans that I could think of.

2025-01-12ocfs2: handle a symlink read error correctlyMatthew Wilcox (Oracle)
Patch series "Convert ocfs2 to use folios". Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-) So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code! This patch (of 23): If we can't read the buffer, be sure to unlock the page before returning.

2025-01-12ocfs2: replace deprecated simple_strtol with kstrtolDaniel Yang
simple_strtol() ignores overflows and has an awkward interface for error checking. Replace with the recommended kstrtol function leads to clearer error checking and safer conversions.

2025-01-12fs/proc: fix softlockup in __read_vmcore (part 2)Rik van Riel
Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the number of softlockups in __read_vmcore at kdump time have gone down, but they still happen sometimes. In a memory constrained environment like the kdump image, a softlockup is not just a harmless message, but it can interfere with things like RCU freeing memory, causing the crashdump to get stuck. The second loop in __read_vmcore has a lot more opportunities for natural sleep points, like scheduling out while waiting for a data write to happen, but apparently that is not always enough. Add a cond_resched() to the second loop in __read_vmcore to (hopefully) get rid of the softlockups.

2025-01-10NFSD: Insulate nfsd4_encode_fattr4() from page boundaries in the encode bufferChuck Lever
Commit ab04de60ae1c ("NFSD: Optimize nfsd4_encode_fattr()") replaced the use of write_bytes_to_xdr_buf() because it's expensive and the data items to be encoded are already properly aligned. However, there's no guarantee that the pointer returned from xdr_reserve_space() will still point to the correct reserved space in the encode buffer after one or more intervening calls to xdr_reserve_space(). It just happens to work with the current implementation of xdr_reserve_space(). This commit effectively reverts the optimization.
