Subject: [GIT PULL] Btrfs updates for 6.8
Hi,
there are no exciting changes for users, it's been mostly API
conversions and some fixes or refactoring. The mount API conversion is
a base for future improvements that would come with VFS. Metadata
processing has been converted to folios, not yet enabling the large
folios but it's one patch away once everything gets tested enough.
There are possible minor merge conflicts reported by linux-next.
Please pull, thanks.
Core changes:
- convert extent buffers to folios
- direct API conversion where possible
- performance can drop by a few percent on metadata heavy workloads,
the folio sizes are not constant and the calculations add up in the
item helpers
- both regular and subpage modes
- data cannot be converted yet, we need to port that to iomap and
there are some other generic changes required
- convert mount to the new API, there should be no user visible change
- options deprecated long time ago have been removed: inode_cache,
recovery
- the new logic that splits mount to two phases slightly changes
timing of device scanning for multi-device filesystems
- LSM options will now work (like for selinux), previous fix attempt
https://lore.kernel.org/selinux/20210316144823.2188946-1-omosnace@redhat.com/
- convert delayed nodes radix tree to xarray, preserving the
preload-like logic that still allows to allocate with GFP_NOFS
- more validation of sysfs value of scrub_speed_max
- refactor chunk map structure, reduce size and improve performance
- extent map refactoring, smaller data structures, improved performance
- reduce size of struct extent_io_tree, embedded in several structures
- temporary pages used for compression are cached and attached to a
shrinker, this may slightly improve performance
- in zoned mode, remove redirty extent buffer tracking, zeros are
written in case an out-of-order is detected and proper data are
written to the actual write pointer
- cleanups, refactoring, error message improvements, updated tests
- verify and update branch name or tag
- remove unwanted text
