David Sterba Sept. 16, 2019, 11:55 a.m. UTC

this update continues with work on code refactoring, sanity checks and
space handling. There are some less user visible changes, nothing that
would particularly stand out.

Please pull, thanks.

User visible changes:

- tree checker, more sanity checks of:
  - ROOT_ITEM (key, size, generation, level, alignment, flags)
  - EXTENT_ITEM and METADATA_ITEM checks (key, size, offset, alignment,
  - tree block reference items
  - EXTENT_DATA_REF (key, hash, offset)

- deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation ioctl,
  scheduled removal in 5.7

- delete stale and unused UAPI definitions BTRFS_DEV_REPLACE_ITEM_STATE_*

- improved export of debugging information available via existing sysfs
  directory structure

- try harder to delete relations between qgroups and allow to delete
  orphan entries

- remove unreliable space checks before relocation starts


- space handling:
  - improved ticket reservations and other high level logic in order to
    remove special cases
  - factor flushing infrastructure and use it for different contexts,
    allows to remove some special case handling
  - reduce metadata reservation when only updating inodes
  - reduce global block reserve minimum size (affects small filesystems)
  - improved overcommit logic wrt global block reserve

- tests:
  - fix memory leaks in extent IO tree
  - catch all TRIM range


- fix ENOSPC errors, leading to transaction aborts, when cloning extents

- several fixes for inode number cache (mount option inode_cache)

- fix potential soft lockups during send when traversing large trees

- fix unaligned access to space cache pages with SLUB debug on (PowerPC)


- refactoring public/private functions, moving to new or more appropriate

- defines converted to enums

- error handling improvements

- more assertions and comments

- old code deletion
