--- Comment #1 from Dmitry Monakhov <dmonakhov@...nvz.org> ---
In fact this is not ext4's issue, this is generic fs issue.
pipe_write() do not accuire sb_start_write(), as far as I understand this is
because pipe should not touch fs's data. But it is not completely correct
because pipe want update file's time. Let's use same trick as we use in
touch_time()
pipe_write will call sb_start_write_try() and skip time update on frozen fs.
See proposed patch.
