The subpage block size and zoned mode features have reached state where they're usable but with limitations. Performance or related: - do not block on deleted block group mutex in the cleaner, avoids some long stalls - improved flushing: make it work better with ticket space reservations and avoid excessive transaction commits in some scenarios, slightly improves throughput for random write load - preemptive background flushing: separate the logic from ticket reservations, improve the accounting and decisions when to flush in low space conditions - less lock contention related to running delayed refs, let just one thread do the flushing when there are many inside transaction commit - dbench workload improvements: avoid unnecessary work when logging inodes, fewer fallbacks to transaction commit and thus less waiting for it (+7% throughput, -20% latency) Core: - subpage block size - currently read-only support - refactor and generalize code where sectorsize is assumed to be page size, add the subpage handling everywhere - the read-write support is on the way, page sizes are still limited to 4K or 64K - zoned mode, first working version but with limitations - SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed location for structures" and chunked allocation - superblock as the only fixed data structure needs special handling, uses 2 consecutive zones as a ring buffer - tree-log support with a dedicated block group to avoid unordered writes - emulated zones on non-zoned devices - not yet working - all non-single block group profiles, requires more zone write pointer synchronization between the multiple block groups - fitrim due to dependency on space cache, can be implemented Fixes: - ref-verify: proper tree owner and node level tracking - fix pinned byte accounting, causing some early ENOSPC now more likely due to other changes in delayed refs Other: - error handling fixes and improvements - more error injection points - more function documentation - more and updated tracepoints - subset of W=1 checked by default - update comments to allow more automatic kdoc parameter checks" * tag 'for-5.12-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (144 commits) btrfs: zoned: enable to mount ZONED incompat flag btrfs: zoned: deal with holes writing out tree-log pages btrfs: zoned: reorder log node allocation on zoned filesystem btrfs: zoned: serialize log transaction on zoned filesystems btrfs: zoned: extend zoned allocator to use dedicated tree-log block group btrfs: split alloc_log_tree() btrfs: zoned: relocate block group to repair IO failure in zoned filesystems btrfs: zoned: enable relocation on a zoned filesystem btrfs: zoned: support dev-replace in zoned filesystems btrfs: zoned: implement copying for zoned device-replace btrfs: zoned: implement cloning for zoned device-replace btrfs: zoned: mark block groups to copy for device-replace btrfs: zoned: do not use async metadata checksum on zoned filesystems btrfs: zoned: wait for existing extents before truncating btrfs: zoned: serialize metadata IO btrfs: zoned: introduce dedicated data write path for zoned filesystems btrfs: zoned: enable zone append writing for direct IO btrfs: zoned: use ZONE_APPEND write for zoned mode btrfs: save irq flags when looking up an ordered extent btrfs: zoned: cache if block group is on a sequential zone ...		2021-02-21 10:00:39 -08:00
