  "message": "ocfs2: update inode size after zeroing the hole\n\nfs-writeback will release the dirty pages without page lock whose offset\nare over inode size, the release happens at\nblock_write_full_page_endio().  If not update, dirty pages in file holes\nmay be released before flushed to the disk, then file holes will contain\nsome non-zero data, this will cause sparse file md5sum error.\n\nTo reproduce the bug, find a big sparse file with many holes, like vm\nimage file, its actual size should be bigger than available mem size to\nmake writeback work more frequently, tar it with -S option, then keep\nuntar it and check its md5sum again and again until you get a wrong\nmd5sum.\n\nSigned-off-by: Junxiao Bi \u003cjunxiao.bi@oracle.com\u003e\nCc: Younger Liu \u003cyounger.liu@huawei.com\u003e\nReviewed-by: Mark Fasheh \u003cmfasheh@suse.de\u003e\nCc: Joel Becker \u003cjlbec@evilplan.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
