These 2 patches are a second pass to add a statx command to xfs_io in hopes that it will aid creation of xfstests statx regression tests. xfs_io> help statx statx [-O | -m mask][-FDLA] -- extended information about the currently open file Display extended file status. Options: -m mask -- Specify the field mask for the statx call (default STATX_ALL) -A -- Suppress terminal automount traversal -D -- Don't sync attributes with the server -F -- Force the attributes to be sync'd with the server -L -- Follow symlinks (statx link target) -O -- Add only basic stats (STATX_BASIC_STATS) to default mask xfs_io> statx stx_mask: 0xfff stx_blksize: 4096 stx_attributes: 0x70 stx_nlink: 1 stx_uid: 0 stx_gid: 0 stx_mode: 0100644 stx_ino: 99 stx_size: 0 stx_blocks: 0 stx_atime.tv_sec: 1490109633 stx_atime.tv_nsec: 676550238 stx_btime.tv_sec: 1490109633 stx_btime.tv_nsec: 675550234 stx_ctime.tv_sec: 1490109725 stx_ctime.tv_nsec: 69966839 stx_mtime.tv_sec: 1490109633 stx_mtime.tv_nsec: 676550238 stx_rdev_major: 0 stx_rdev_minor: 0 stx_dev_major: 7 stx_dev_minor: 0 patch 2 includes a header file with lots of the new #defines so this can build on older systems; eventually that can be removed perhaps. An interesting limitation of all of the xfs_io stat variants is that they currently can't stat any file that they can't open, which may or may not be a limitation that we care about.... -Eric
