Hi all,

This patchset adds new ioctl for setting/getting inode extended
attributes on fs inodes, useful for special files which return VFS
inode on open() and therefore FS_IOC_FSSETXATTR can not be used.
This roots from xfs_quota not being able to set project IDs on
special files [1].

Andrey Albershteyn (4):
  xfs: allow renames of project-less inodes
  fs: add FS_IOC_FSSETXATTRAT and FS_IOC_FSGETXATTRAT
  xfs: allow setting xattrs on special files
  xfs: add fileattr_set/get for symlinks
