Hi Jens, A couple of patches for 4.15. Javier has improved garbage collection, statistics, memory pool usage, and added support for single LUN configurations. He also made a lot of bug fixes and cleanup patches. Rakesh have been fixing up a lot of subsystem bugs with respect to loading and unloading pblk, cleanup of memory pools, and a couple of fixes spread across the lightnvm subsystem and pblk. Hans has been looking into garbage collection, and shutting it down gracefully when pblk is unloaded. Please pull from the for-4.15/for-jens branch or apply the patches posted with this thread: https://github.com/OpenChannelSSD/linux.git for-4.15/for-jens Thanks, Matias Hans Holmberg (10): lightnvm: pblk: prevent gc kicks when gc is not operational lightnvm: pblk: recover partially written lines correctly lightnvm: pblk: free full lines during recovery lightnvm: pblk: start gc if needed during init lightnvm: pblk: consider bad sectors in emeta during recovery lightnvm: pblk: shut down gc gracefully during exit lightnvm: pblk: add l2p crc debug printouts lightnvm: pblk: gc all lines in the pipeline before exit lightnvm: pblk: correct valid lba count calculation lightnvm: pblk: remove spinlock when freeing line metadata Javier González (31): lightnvm: pblk: initialize debug stat counter lightnvm: pblk: use right flag for GC allocation lightnvm: pblk: free padded entries in write buffer lightnvm: pblk: fix write I/O sync stat lightnvm: pblk: avoid deadlock on low LUN config lightnvm: pblk: fix min size for page mempool lightnvm: pblk: simplify work_queue mempool lightnvm: pblk: decouple read/erase mempools lightnvm: pblk: do not use a mempool for line bitmaps lightnvm: pblk: remove checks on mempool alloc. lightnvm: pblk: use constant for GC max inflight lightnvm: pblk: normalize ppa namings lightnvm: pblk: refactor read lba sanity check lightnvm: pblk: simplify data validity check on GC lightnvm: pblk: refactor read path on GC lightnvm: pblk: put bio on bio completion lightnvm: pblk: simplify path on REQ_PREFLUSH lightnvm: pblk: allocate bio size more accurately lightnvm: pblk: improve naming for internal req. lightnvm: pblk: refactor rqd alloc/free lightnvm: pblk: use rqd->end_io for completion lightnvm: pblk: check lba sanity on read path lightnvm: pblk: guarantee line integrity on reads lightnvm: pblk: remove redundant check on read path lightnvm: pblk: remove I/O dependency on write path lightnvm: pblk: enable 1 LUN configuration lightnvm: pblk: ensure right bad block calculation lightnvm: pblk: cleanup unused and static functions lightnvm: pblk: avoid being reported as hung on rated GC lightnvm: fail fast on passthrough commands lightnvm: implement generic path for sync I/O Rakesh Pandit (17): lightnvm: prevent target type module removal when in use lightnvm: prevent bd removal if busy lightnvm: protect target type list with correct locks lightnvm: remove already calculated nr_chnls lightnvm: pblk: fix error path in pblk_lines_alloc_metadata lightnvm: include NVM Express driver if OCSSD is selected for build lightnvm: pblk: protect line bitmap while submitting meta io lightnvm: pblk: fix message if L2P MAP is in device lightnvm: pblk: improve error message if down_timeout fails lightnvm: pblk: print incompatible line version correctly lightnvm: pblk: reuse pblk_gc_should_kick lightnvm: pblk: fix changing GC group list for a line lightnvm: pblk: remove useless line lightnvm: remove unused argument from nvm_set_tgt_bb_tbl lightnvm: remove stale extern and unused exported symbols lightnvm: pblk: reduce arguments in __pblk_rb_update_l2p lightnvm: pblk: fix releases of kmem cache in error path drivers/lightnvm/Kconfig | 3 +- drivers/lightnvm/core.c | 190 +++++++------- drivers/lightnvm/pblk-cache.c | 24 +- drivers/lightnvm/pblk-core.c | 516 ++++++++++++++++++++------------------- drivers/lightnvm/pblk-gc.c | 311 ++++++++++++----------- drivers/lightnvm/pblk-init.c | 197 +++++++++------ drivers/lightnvm/pblk-map.c | 28 ++- drivers/lightnvm/pblk-rb.c | 30 +-- drivers/lightnvm/pblk-read.c | 274 ++++++++++++--------- drivers/lightnvm/pblk-recovery.c | 131 ++++------ drivers/lightnvm/pblk-rl.c | 43 +--- drivers/lightnvm/pblk-sysfs.c | 2 +- drivers/lightnvm/pblk-write.c | 229 +++++++---------- drivers/lightnvm/pblk.h | 137 +++++++---- drivers/nvme/host/lightnvm.c | 72 ++++-- include/linux/lightnvm.h | 11 +- 16 files changed, 1172 insertions(+), 1026 deletions(-) -- 2.9.3
