[JFFS2][XATTR] using 'delete marker' for xdatum/xref deletion
- When xdatum is removed, a new xdatum with 'delete marker' is written. (version==0xffffffff means 'delete marker') - When xref is removed, a new xref with 'delete marker' is written. (odd-numbered xseqno means 'delete marker') - delete_xattr_(datum/xref)_delay() are new deletion functions are added. We can only use them if we can detect the target obsolete xdatum/xref as a orphan or errir one. (e.g when inode deletion, or detecting crc error) [1/3] jffs2-xattr-v6-01-delete_marker.patch Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
