Linus Torvalds fe41c2c018 A set of device-mapper changes for 3.14. ... A lot of attention was paid to improving the thin-provisioning target's handling of metadata operation failures and running out of space. A new 'error_if_no_space' feature was added to allow users to error IOs rather than queue them when either the data or metadata space is exhausted. Additional fixes/features include: - a few fixes to properly support thin metadata device resizing - a solution for reliably waiting for a DM device's embedded kobject to be released before destroying the device - old dm-snapshot is updated to use the dm-bufio interface to take advantage of readahead capabilities that improve snapshot activation - new dm-cache target tunables to control how quickly data is promoted to the cache (fast) device - improved write efficiency of cluster mirror target by combining userspace flush and mark requests -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJS4GClAAoJEMUj8QotnQNacdEH/2ES5k5itUQRY9jeI+u2zYNP vdsRTYf+97+B3jpRvpWbMt4kxT2tjaQbkxJ+iKRHy2MBLFUgq8ruH1RS/Q5VbDeg 6i6ol8mpNxhlvo/KTMxXqRcWDSxShiMfhz2lXC2bJ7M4sP/iiH85s4Pm4YQ59jpd OIX7qj36m/cV/le9YQbexJEEsaj+3genbzL26wyyvtG/rT9fWnXa7clj2gqTdToG YCEBCRf5FH9X6W/Oc50nMw5n2dt/MRmPre/MAlOjemeaosB0WJiKaswM25rnvHp0 JnhxQ2K2C5KIKAWIfwPOImdb9zWW7p1dIRLsS8nHBUQr0BF5VRkmvpnYH4qBtcc= =e7e0 -----END PGP SIGNATURE----- Merge tag 'dm-3.14-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device-mapper changes from Mike Snitzer: "A lot of attention was paid to improving the thin-provisioning target's handling of metadata operation failures and running out of space.
