Andrey Smetanin (38):
ploop: fix accounting ploop_io_images_size
ploop: fix dio_fsync wait
ploop: check new size of block device on ioctl(GROW)
ploop: prevent dangerous ploop-umount
ploop: prevent disclosure 4 bytes of the stack kernel
ploop: report holes in pio_direct (v2)
ploop: rework accounting images_size
ploop: fix iblk-to-sector calculations
ploop: fix sync delay for sync requests
ploop: reverse order of fdatawait and fsync fop
ploop: skip writes of zeroes to unallocated blocks by default
ploop: support 4K block-size of host block-device
ploop: fix a race condition on relocation of blocks
ploop: fix check_zero optimization v2
ploop: fix race in ploop_tracker_init()
ploop: prioritize BAT operations
ploop: add ioctl to limit size of top delta (v2)
ploop: bug on bad fiemap (v2)
ploop: ensure non-empty delta list on running ploop
ploop: expose open_count to sysfs
ploop: fix spurious hole complains
ploop: put top-delta back if merge failed
ploop: roll back alloc_head on ENOSPC
ploop: zero blocks on reuse
ploop: make manual abort transition verbose
ploop: warning on "disk full" condition
ploop: add a separate queue for discard bio-s (v2)
ploop: notify blktrace about bio completions
ploop: fix busyloop on secondary discard bio
Series description:
ploop: define struct ploop_request->state flags to force pre FLUSH
before write IO and FUA/fsync at I/O complete
ploop: direct: to support truly FLUSH/FUA of req we need mark first
bio FLUSH, write all bios and mark last bio as FLUSH/FUA
ploop: do preflush or postfua according force FUA/flush flags, and
delay FUA if possible but add force FLUSH to req if so
ploop: make image fsync at I/O complete if it's required by FUA/fsync
force flag or by req->req_rw
ploop: mark reloc reqs to force FUA before write of relocated data
ploop: mark reloc reqs to force FUA/fsync(kaio) for index update I/O
ploop: force FUA of nullified blocks for BAT grow
ploop: added printk of function, line, backtrace before
