Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix reflink preserve cleanup issue
commit c06c303832ec ("ocfs2: fix xattr array entry __counted_by error")
doesn't handle all cases and the cleanup job for preserved xattr entries
still has bug:
- the 'last' pointer should be shifted by one unit after cleanup
an array entry.
- current code logic doesn't cleanup the first entry when xh_count is 1.
Note, commit c06c303832ec is also a bug fix for 0fe9b66c65f3.
