New code for 5.5: - Fill out the build string - Prevent inode fork extent count overflows - Refactor the allocator to reduce long tail latency - Rework incore log locking a little to reduce spinning - Break up the xfs_iomap_begin functions into smaller more cohesive parts - Fix allocation alignment being dropped too early when the allocation request is for more blocks than an AG is large - Other small cleanups - Clean up file buftarg retrieval helpers - Hoist the resvsp and unresvsp ioctls to the vfs - Remove the undocumented biosize mount option, since it has never been mentioned as existing or supported on linux - Clean up some of the mount option printing and parsing - Enhance attr leaf verifier to check block structure - Check dirent and attr names for invalid characters before passing them to the vfs - Refactor open-coded bmbt walking - Fix a few places where we return EIO instead of EFSCORRUPTED after failing metadata sanity checks - Fix a synchronization problem between fallocate and aio dio corrupting the file length - Clean up various loose ends in the iomap and bmap code - Convert to the new mount api - Make sure we always log something when returning EFSCORRUPTED - Fix some problems where long running scrub loops could trigger soft lockup warnings and/or fail to exit due to fatal signals pending - Fix various Coverity complaints - Remove most of the function pointers from the directory code to reduce indirection penalties - Ensure that dquots are attached to the inode when performing unwritten extent conversion after io - Deuglify incore projid and crtime types - Fix another AGI/AGF locking order deadlock when renaming - Clean up some quota typedefs - Remove the FSSETDM ioctls which haven't done anything in 20 years
