vfs: Add IOP_XATTR inode operations flag
The IOP_XATTR inode operations flag in inode->i_opflags indicates that the inode has xattr support. The flag is automatically set by new_inode() on filesystems with xattr support (where sb->s_xattr is defined), and cleared otherwise. Filesystems can explicitly clear it for inodes that should not have xattr support. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
