Merge tag 'xfs-for-linus-3.17-rc1' of git://oss.sgi.com/xfs/xfs
Pull xfs update from Dave Chinner: "This update contains: - conversion of the XFS core to pass negative error numbers - restructing of core XFS code that is shared with userspace to fs/xfs/libxfs - introduction of sysfs interface for XFS - bulkstat refactoring - demand driven speculative preallocation removal - XFS now always requires 64 bit sectors to be configured - metadata verifier changes to ensure CRCs are calculated during log recovery - various minor code cleanups - miscellaneous bug fixes The diffstat is kind of noisy because of the restructuring of the code to make kernel/userspace code sharing simpler, along with the XFS wide change to use the standard negative error return convention (at last!)" * tag 'xfs-for-linus-3.17-rc1' of git://oss.sgi.com/xfs/xfs: (45 commits) xfs: fix coccinelle warnings xfs: flush both inodes in xfs_swap_extents xfs: fix swapext ilock deadlock xfs: kill xfs_vnode.h xfs: kill VN_MAPPED xfs: kill VN_CACHED xfs: kill VN_DIRTY() xfs: dquot recovery needs verifiers xfs: quotacheck leaves dquot buffers without verifiers xfs: ensure verifiers are attached to recovered buffers xfs: catch buffers written without verifiers attached xfs: avoid false quotacheck after unclean shutdown xfs: fix rounding error of fiemap length parameter xfs: introduce xfs_bulkstat_ag_ichunk xfs: require 64-bit sector_t xfs: fix uflags detection at xfs_fs_rm_xquota xfs: remove XFS_IS_OQUOTA_ON macros xfs: tidy up xfs_set_inode32 xfs: allow inode allocations in post-growfs disk space xfs: mark xfs_qm_quotacheck as static ...
