Revision 22c8ca78f20724676b6006232bf06cc3e9299539 authored by Nick Piggin on 20 February 2007, 21:58:09 UTC, committed by Linus Torvalds on 21 February 2007, 01:10:15 UTC
nobh_prepare_write leaks data similarly to how simple_prepare_write did. Fix by not marking the page uptodate until nobh_commit_write time. Again, this could break weird use-cases, but none appear to exist in the tree. We can safely remove the set_page_dirty, because as the comment says, nobh_commit_write does set_page_dirty. If a filesystem wants to allocate backing store for a page dirtied via mmap, page_mkwrite is the suggested approach.
