BUG at mm/page-writeback.c:2164
2160 int clear_page_dirty_for_io(struct page *page)
2161 {
2162 struct address_space *mapping = page_mapping(page);
2163
2164 BUG_ON(!PageLocked(page));
btrfs on the stack is only __btrfs_buffered_write +
btrfs_file_aio_write, ie. just a buffered write, originating from
pwrite64.
The bug_on condition is clear, the question is why the page is not
locked.
