dm thin: Use last transaction's pmd->root when commit failed (2022-12-08 12:17:09 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Fix use-after-free races due to missing resource cleanup during DM
target destruction in DM targets: thin-pool, cache, integrity and
clone.
- Fix ABBA deadlocks in DM thin-pool and cache targets due to their
use of a bufio client (that has a shrinker whose locking can cause
the incorrect locking order).
- Fix DM cache target to set its needs_check flag after first aborting
the metadata (whereby using reset persistent-data objects to update
the superblock with, otherwise the superblock update could be
dropped due to aborting metadata). This was found with
code-inspection when comparing with the equivalent in DM thinp
code.
- Fix DM thin-pool's presume to continue resuming the device even if
the pool in is fail mode -- otherwise bios may never be failed up
the IO stack (which will prevent resetting the thin-pool target via
table reload)
- Fix DM thin-pool's metadata to use proper btree root (from previous
transaction) if metadata commit failed.
- Add 'waitfor' module param to DM module (dm_mod) to allow dm-init to
wait for the specified device before continuing with its DM target
initialization.
