Merge tag 'for-4.19/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer: - DM verity fix for crash due to using vmalloc'd buffers with the asynchronous crypto hadsh API. - Fix to both DM crypt and DM integrity targets to discontinue using CRYPTO_TFM_REQ_MAY_SLEEP because its use of GFP_KERNEL can lead to deadlock by recursing back into a filesystem. - Various DM raid fixes related to reshape and rebuild races. - Fix for DM thin-provisioning to avoid data corruption that was a side-effect of needing to abort DM thin metadata transaction due to running out of metadata space. Fix is to reserve a small amount of metadata space so that once it is used the DM thin-pool can finish its active transaction before switching to read-only mode. * tag 'for-4.19/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin metadata: try to avoid ever aborting transactions dm raid: bump target version, update comments and documentation dm raid: fix RAID leg rebuild errors dm raid: fix rebuild of specific devices by updating superblock dm raid: fix stripe adding reshape deadlock dm raid: fix reshape race on small devices dm: disable CRYPTO_TFM_REQ_MAY_SLEEP to fix a GFP_KERNEL recursion deadlock dm verity: fix crash on bufio buffer that was allocated with vmalloc
