In the Linux kernel, the following vulnerability has been resolved:
ceph: fix a buffer leak in __ceph_setxattr()
The old_blob in __ceph_setxattr() can store
ci->i_xattrs.prealloc_blob value during the retry.
However, it is never called the ceph_buffer_put()
for the old_blob object. This patch fixes the issue of
the buffer leak.
