Set is not to be considered finished.
- BAT writeback delay
- Lists/Locking moving to lockless lists to reduce locking
- Requests are prepared in the caller to reduce load of worker thread
- REQ_FUA and REQ_PREFLUSH support
- Convert bit fields to use atomic bitops - reduce locking
- remove fsync worker to guarantee order of execution
- Map all md pages at creation time - they are only freed on device destroy
Alexander Atanasov (20):
dm-ploop: md_pages map all pages at creation time
dm-ploop: Use READ_ONCE/WRITE_ONCE to access md page data
dm-ploop: fsync after all pios are sent
dm-ploop: move md status to use proper bitops
dm-ploop: remove unneccessary lock
dm-ploop: reduce the time lock is hold, taking it only to protect data
dm-ploop: convert wait_list and wb_batch_llist to use lockless lists
dm-ploop: convert enospc handling to use lockless lists
dm-ploop: convert suspended_pios list to use lockless list
dm-ploop: convert the rest of the lists to use llist variant
dm-ploop: combine processing of pios thru prepare list and remove
fsync worker
dm-ploop: WIP move from wq to kthread
dm-ploop: complete conversion of enospc and suspended pios to lockless
dm-ploop: move preparations of pios into the caller from worker
dm-ploop: fast path execution for reads
dm-ploop: do not use a wrapper for set_bit to make a page writeback
dm-ploop: BAT use only one list for writeback
dm-ploop: make md writeback timeout to be per page
dm-ploop: add interface to disable bat writeback delay
dm-ploop: convert wb_batch_list to lockless variant
Andrey Zhadchenko (13):
dm-ploop: do not flush after metadata writes
dm-ploop: set IOCB_DSYNC on all FUA requests
dm-ploop: remove extra ploop_cluster_is_in_top_delta()
dm-ploop: simplify llseek
dm-ploop: reduce BAT accesses on discard completion
dm-ploop: introduce per-md page locking
dm-ploop: speed up ploop_prepare_bat_update()
dm-ploop: make new allocations immediately visible in BAT
dm-ploop: drop ploop_cluster_is_in_top_delta()
dm-ploop: do not wait for BAT update for non-FUA requests
dm-ploop: add delay for metadata writeback
dm-ploop: submit all postponed metadata on REQ_OP_FLUSH
dm-ploop: handle REQ_PREFLUSH
