Here we have defrag support for v5 superblock, a number of bugfixes and a cleanup or two. - defrag support for CRC filesystems - fix endian worning in xlog_recover_get_buf_lsn - fixes for sparse warnings - fix for assert in xfs_dir3_leaf_hdr_from_disk - fix for log recovery of remote symlinks - fix for log recovery of btree root splits - fixes formemory allocation failures with ACLs - fix for assert in xfs_buf_item_relse - fix for assert in xfs_inode_buf_verify - fix an assignment in an assert that should be a test in xfs_bmbt_change_owner - remove dead code in xlog_recover_inode_pass2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJSMjQUAAoJENaLyazVq6ZOu2IP/1OHZYy+Bkmj0tO9pdsdEa4s w4FEBPsQePMJPjwdN693rKpW1exZue5sUmPMErH3ENzc2DPAwpUAlc9XAIohtdFx rTqrz2q+qTfZTq8oYBIA/RCOifJ2cHWN8tDYZPJpp5wceV7CRGYQeR1foiudE3ZH QDIPXioy8P9IkfGaXCtr/iWf9kycMO2lgNTNfdL6qtwX99HCqHZanTlsWx1BIYGQ Fa5TaOsXis6idPMCFMuEC15iEwA+YXc0HmXuHkMFLj+9mwFc4h/Aq65bwUkYZLmy +T1Wo/uQ/21rl6im/rWqgCh6fFS8NJQp8NIJeCIyihUEHbarfPyJIJRJjoP457YO cv8OkixCkt4zX6CkTxaL5ZFEBW9FYbRb13Gg96J6hb4WfdAFMtQg7FAjThSU/+Qr HwjaAso3GXimEaZD1C3c0TtZEQ0x9E6pENVI7/ewB1I0p92p7GJBMq4C7CTAYThV 5zhdcOnViSrJTJvVQxm+gfOYzubkWWiVmbVku3RCO6//kvPBOvJ9juSYsl0mKeRu v2DZZB3AYJE/qnbYfZBlktX9obE6k+keKF6w8Eiufr2IqwJaqfaM4h9eogzAwTJA vyXKeLxUEmgHuqivFSZjw3sEK6sY654GCMMTP+2IpD19vlAIioYXdgp0ZbkkdiE3 6twrzdFZAr1zy80xlM8W =2Uq6 -----END PGP SIGNATURE----- Merge tag 'xfs-for-linus-v3.12-rc1-2' of git://oss.sgi.com/xfs/xfs Pull xfs update #2 from Ben Myers: "Here we have defrag support for v5 superblock, a number of bugfixes and a cleanup or two. - defrag support for CRC filesystems - fix endian worning in xlog_recover_get_buf_lsn - fixes for sparse warnings - fix for assert in xfs_dir3_leaf_hdr_from_disk - fix for log recovery of remote symlinks - fix for log recovery of btree root splits - fixes formemory allocation failures with ACLs - fix for assert in xfs_buf_item_relse - fix for assert in xfs_inode_buf_verify - fix an assignment in an assert that should be a test in xfs_bmbt_change_owner - remove dead code in xlog_recover_inode_pass2" * tag 'xfs-for-linus-v3.12-rc1-2' of git://oss.sgi.com/xfs/xfs: xfs: remove dead code from xlog_recover_inode_pass2 xfs: = vs == typo in ASSERT() xfs: don't assert fail on bad inode numbers xfs: aborted buf items can be in the AIL. xfs: factor all the kmalloc-or-vmalloc fallback allocations xfs: fix memory allocation failures with ACLs xfs: ensure we copy buffer type in da btree root splits xfs: set remote symlink buffer type for recovery xfs: recovery of swap extents operations for CRC filesystems xfs: swap extents operations for CRC filesystems xfs: check magic numbers in dir3 leaf verifier first xfs: fix some minor sparse warnings xfs: fix endian warning in xlog_recover_get_buf_lsn()
