  "message": "fs/mpage.c: fix mpage_writepage() for pages with buffers\n\nWhen using FAT on a block device which supports rw_page, we can hit\nBUG_ON(!PageLocked(page)) in try_to_free_buffers().  This is because we\ncall clean_buffers() after unlocking the page we\u0027ve written.  Introduce\na new clean_page_buffers() which cleans all buffers associated with a\npage and call it from within bdev_write_page().\n\n[akpm@linux-foundation.org: s/PAGE_SIZE/~0U/ per Linus and Matthew]\nLink: http://lkml.kernel.org/r/20171006211541.GA7409@bombadil.infradead.org\nSigned-off-by: Matthew Wilcox \u003cmawilcox@microsoft.com\u003e\nReported-by: Toshi Kani \u003ctoshi.kani@hpe.com\u003e\nReported-by: OGAWA Hirofumi \u003chirofumi@mail.parknet.co.jp\u003e\nTested-by: Toshi Kani \u003ctoshi.kani@hpe.com\u003e\nAcked-by: Johannes Thumshirn \u003cjthumshirn@suse.de\u003e\nCc: Ross Zwisler \u003cross.zwisler@linux.intel.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
