xfs: update for 3.9-rc1
For 3.9-rc1 there are primarily bugfixes and a few cleanups. - fix(es) for compound buffers - remove unused XFS_TRANS_DEBUG routines - fix for dquot soft timer asserts due to overflow of d_blk_softlimit - don't zero allocation args structure members after they are memset(0) - fix for regression in dir v2 code introduced in commit20f7e9f3
- remove obsolete simple_strto<foo> - fix return value when filesystem probe finds no XFS magic, a regression introduced in9802182
. - remove boolean_t typedef completely - fix stack switch in __xfs_bmapi_allocate by moving the check for stack switch up into xfs_bmapi_write. - fix build error due to incomplete boolean_t removal - fix oops in _xfs_buf_find by validating that the requested block is within the filesystem bounds. - limit speculative preallocation near ENOSPC. - fix an unmount hang in xfs_wait_buftarg by freeing the xfs_buf_log_item in xfs_buf_item_unlock. - fix a possible use after free with AIO. - fix xfs_swap_extents after removal of xfs_flushinval_pages, a regression introduced infb59581404
. - replace hardcoded 128 with log header size - add memory barrier before wake_up_bit in xfs_ifunlock - limit speculative preallocation on sparse files - fix xa_lock recursion bug introduced in90810b9e82
- fix write verifier for symlinks -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJRI/pkAAoJENaLyazVq6ZO8F0QAMUgw+edrht4x/vr0stNpLvL /htIhJVhRjWthQaSiUkmlHShNZCgvfKSRPG9OiaMo24QuqardB3Ieh90JTW8b5Iu 63tQ1kKB++n1PnW7OYSxvUj2WNBHwHlI0ueNUiEFXoD9tQOWcyO63CxA/qnTJB1P gulI+R7gWafqD1UpH6kP/xCMn3V3PnCYVdX2LJHuEjQoCydsKgtc9dgvRi4e51kf OrxnKof6tAlkpNc1+ZmoQch4NS+jRWv90HGdrxOy/BESC0QYSyfrAwxXIVvkwBfu NsQg5oDCp4jlDQt9gjgABhPcWvSGc7JhSjqbXTnweRS4t7SOGGvb46HVrLMKZRID MFT8tbc1HXzAl2z2k0S0bRy9HNC4QZg5GJZ/MhXMKUQWZLZf/XPALgQ5q95hEjsc MUTudN7Xa8Ay+2BPTI34M3f1Mlzmm68N07rzjw8jmJzjVq8v7LJ1wbmpiswjkHiW 6u6MSwY3NDhjNI0sA+h6ByX3KwYfBW9Y63QI/8Dld7jDFQ5onxYmkIP+fPe1vhBJ 51gNm7bKXImEFpykAP5YddCnxMWtFUdIH/Wyu7quMpwv5YSIR+zVd3l4edqAKIgh YlJ9bLewWP+4B2L4raotPjdaOxDZfrW2nP0vmVcuQWEbMdANZ8XQTNPCULcoKGtY iBCDlWS7wAfH8PYnXlbp =/Zui -----END PGP SIGNATURE----- Merge tag 'for-linus-v3.9-rc1' of git://oss.sgi.com/xfs/xfs Pull xfs update from Ben Myers: "Primarily bugfixes and a few cleanups: - fix(es) for compound buffers - remove unused XFS_TRANS_DEBUG routines - fix for dquot soft timer asserts due to overflow of d_blk_softlimit - don't zero allocation args structure members after they are memset(0) - fix for regression in dir v2 code introduced in commit20f7e9f3
