Subject: [GIT PULL] Btrfs updates for 4.17
Hi,
please pull the following btrfs changes. There are a several user
visible changes, the rest is mostly invisible and continues to clean up
the whole code base.
There are no merge conflicts with current master. Please pull, thanks.
User visible changes:
- new mount option nossd_spread (pair for ssd_spread)
- mount option subvolid will detect junk after the number and fail the mount
- add message after cancelled device replace
- direct module dependency on libcrc32, removed own crc wrappers
- removed user space transaction ioctls
- use lighter locking when reading /proc/self/mounts, RCU instead of mutex
to avoid unnecessary contention
Enhancements:
- skip writeback of last page when truncating file to same size
- send: do not issue unnecessary truncate operations
- mount option token specifiers: use %u for unsigned values, more validation
- selftests: more tree block validations
qgroups:
- preparatory work for splitting reservation types for data and metadata,
this should allow for more accurate tracking and fix some issues with
underflows or do further enhancements
- split metadata reservations for started and joined transaction so they do
not get mixed up and are accounted correctly at commit time
- with the above, it's possible to revert patch that potentially deadlocks
when trying to make more space by explicitly committing when the quota
limit is hit
- fix root item corruption when multiple same source snapshots are created
with quota enabled
RAID56:
- make sure target is identical to source when raid56 rebuild fails after
dev-replace
- faster rebuild during scrub, batch by stripes and not block-by-block
- make more use of cached data when rebuilding from a missing device
Fixes:
- null pointer deref when device replace target is missing
- fix fsync after hole punching when using no-holes feature
- fix lockdep splat when allocating percpu data with wrong GFP flags
Cleanups, refactoring, core changes:
- drop redunant parameters from various functions
- kill and opencode trivial helpers
- __cold/__exit function annotations
- dead code removal
- continued audit and documentation of memory barriers
- error handling: handle removal from uuid tree
- error handling: remove handling of impossible condtitons
- more debugging or error messages
- updated tracepoints
- 1 VLA use removal (1 still left)
