3.16.39-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Maxim Patlasov <[email protected]> commit 9ebce595f63a407c5cec98f98f9da8459b73740a upstream. fuse_flush() calls write_inode_now() that triggers writeback, but actual writeback will happen later, on fuse_sync_writes(). If an error happens, fuse_writepage_end() will set error bit in mapping->flags. So, we have to check mapping->flags after fuse_sync_writes().
