[PATCH] fuse: fuse_flush must check mapping->flags for errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().
