ext4: don't lock the next page in write_cache_pages if not needed If we have accumulated a contiguous region of memory to be written out, and the next page can added to this region, don't bother locking (and then unlocking the page) before writing out the memory. In the unlikely event that the next page was being written back by some other CPU, we can also skip waiting that page to finish writeback. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
