. stable fix for a dm-cache related bug in dm-btree walking code that results from using very large fast device (e.g. 4T) with a very small cache blocksize (e.g. 32K) -- this is a very uncommon configuration . a couple fixes for dm-raid (one for stable and the other addresses a crash in 3.18-rc1 code) . stable fix for dm-thinp that addresses a very rare dm-bufio bug having to do with memory reclaimation (via shrinker) when using dm-thinp ontop of loopback devices . fix a leak in dm-stripe target constructor's error path -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJUY/p7AAoJEMUj8QotnQNaxPEIAJsmJC5ujQAIdm5yUxsOWruU Y/36HbPvlmV8fgWqGyjaubBrzqgWry/yW/u/Sv9+9rE3Zh6JSVLVrCA6uZZ3Yr+j HKYEPjm/O0zVJepfEDKtjG6dxeaql47+luwU1iP1bAYeZE3zmKn1oFT2GW5gTbxO 2n3MiN/dyX8v0cTw6r0O69luIAu93CSY0XDk+1ynfKlKKVmgcAUPvKuobF+yHXoF Rd7KTqFoK6HgRhdUHvUQnCGDandZ9MHjt3oW9p3dv3ezvW1cNUARoVHMRGG6Awfu WZkQ/VORDeaJT+bhjGfPIla1HbgxEKJrgzTUlpj+P6K2uPK2f6ECEyBpDLWKy9g= =lkSu -----END PGP SIGNATURE----- Merge tag 'dm-3.18-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - stable fix for dm-thin that avoids normal IO racing with discard - stable fix for a dm-cache related bug in dm-btree walking code that results from using very large fast device (eg 4T) with a very small cache blocksize (eg 32K) -- this is a very uncommon configuration - a couple fixes for dm-raid (one for stable and the other addresses a crash in 3.18-rc1 code) - stable fix for dm-thinp that addresses a very rare dm-bufio bug having to do with memory reclaimation (via shrinker) when using dm-thinp ontop of loopback devices - fix a leak in dm-stripe target constructor's error path * tag 'dm-3.18-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm btree: fix a recursion depth bug in btree walking code dm thin: grab a virtual cell before looking up the mapping dm raid: fix inaccessible superblocks causing oops in configure_discard_support dm raid: ensure superblock's size matches device's logical block size dm bufio: change __GFP_IO to __GFP_FS in shrinker callbacks dm stripe: fix potential for leak in stripe_ctr error path
