  "message": "ocfs2: Fix possible deadlock when extending quota file\n\nIn OCFS2, allocator locks rank above transaction start. Thus we\ncannot extend quota file from inside a transaction less we could\ndeadlock.\n\nWe solve the problem by starting transaction not already in\nocfs2_acquire_dquot() but only in ocfs2_local_read_dquot() and\nocfs2_global_read_dquot() and we allocate blocks to quota files before starting\nthe transaction.  In case we crash, quota files will just have a few blocks\nmore but that\u0027s no problem since we just use them next time we extend the\nquota file.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n",
