new sysfs exports: # - add sysfs knob to limit scrub IO bandwidth per device # - device stats are also available in # /sys/fs/btrfs/FSID/devinfo/DEVID/error_stats # # - support cancellable resize and device delete ioctls # # - change how the empty value is interpreted when setting a property, # so far we have only 'btrfs.compression' and we need to distinguish # a reset to defaults and setting "do not compress", in general the # empty value will always mean 'reset to defaults' for any other # property, for compression it's either 'no' or 'none' to forbid # compression # # Performance improvements: # # - no need for full sync when truncation does not touch extents, # reported run time change is -12% # # - avoid unnecessary logging of xattrs during fast fsyncs (+17% # throughput, -17% runtime on xattr stress workload) # # Core: # # - preemptive flushing improvements and fixes # - adjust clamping logic on multi-threaded workloads to avoid # flushing too soon # - take into account global block reserve, may help on almost full # filesystems # - continue flushing when there are enough pending delalloc and # ordered bytes # # - simplify logic around conditional transaction commit, a workaround # used in the past for throttling that's been superseded by ticket # reservations that manage the throttling in a better way # # - subpage blocksize preparation: # - submit read time repair only for each corrupted sector # - scrub repair now works with sectors and not pages # - free space cache (v1) works with sectors and not pages # - more fine grained bio tracking for extents # - subpage support in page callbacks, extent callbacks, end io # callbacks # # - simplify transaction abort logic and always abort and don't check # various potentially unreliable stats tracked by the transaction # # - exclusive operations can do more checks when started and allow eg. # cancellation of the same running operation # # - ensure relocation never runs while we have send operations running, # e.g. when zoned background auto reclaim starts # # Fixes: # # - zoned: more sanity checks of write pointer # # - improve error handling in delayed inodes # # - send: # - fix invalid path for unlink operations after parent # orphanization # - fix crash when memory allocations trigger reclaim # # - skip compression of we have only one page (can't make things # better) # # - empty value of a property newly means reset to default # # Other: # # - lots of cleanups, comment updates, yearly typo fixing # # - disable build on platforms having page size 256K" # # * tag 'for-5.14-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (101 commits) # btrfs: remove unused btrfs_fs_info::total_pinned # btrfs: rip out btrfs_space_info::total_bytes_pinned # btrfs: rip the first_ticket_bytes logic from fail_all_tickets # btrfs: remove FLUSH_DELAYED_REFS from data ENOSPC flushing # btrfs: rip out may_commit_transaction # btrfs: send: fix crash when memory allocations trigger reclaim # btrfs: ensure relocation never runs while we have send operations running # btrfs: shorten integrity checker extent data mount option # btrfs: switch mount option bits to enums and use wider type # btrfs: props: change how empty value is interpreted # btrfs: compression: don't try to compress if we don't have enough pages # btrfs: fix unbalanced unlock in qgroup_account_snapshot() # btrfs: sysfs: export dev stats in devinfo directory # btrfs: fix typos in comments # btrfs: remove a stale comment for btrfs_decompress_bio() # btrfs: send: use list_move_tail instead of list_del/list_add_tail # btrfs: disable build on platforms having page size 256K # btrfs: send: fix invalid path for unlink operations after parent orphanization # btrfs: inline wait_current_trans_commit_start in its caller # btrfs: sink wait_for_unblock parameter to async commit # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 122fa8c588316aacafe7e5a393bb3e875eaf5b25 # < make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # < make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 120 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/linus_x86_64_defconfig_x86_64-gcc8 # Build took: 0:01:27.001878
