f2fs: remove set_page_dirty for atomic f2fs_end_io_write
We should guarantee not to do *scheduling while atomic*.
I found, in atomic f2fs_end_io_write(), there is a set_page_dirty() call
to deal with IO errors.
But, set_page_dirty() calls:
-> f2fs_set_data_page_dirty()
-> set_dirty_dir_page()
-> cond_resched() which results in scheduling.
In order to avoid this, I'd like to remove simply set_page_dirty(),
since the page is already marked as ERROR and f2fs will be operated
as the read-only mode as well.
So, there is no recovery issue with this.
