I'm looking at this part of 2.4.2-ac8:
diff -u --new-file --recursive --exclude-from /usr/src/exclude linux-2.4.0/mm/filemap.c linux.ac/mm/filemap.c --- linux-2.4.0/mm/filemap.c Wed Jan 3 02:59:45 2001 +++ linux.ac/mm/filemap.c Thu Jan 11 17:26:55 2001 @@ -206,6 +206,9 @@ if (!page->buffers || block_flushpage(page, 0)) lru_cache_del(page);
+ if (page->mapping->a_ops->truncatepage) + page->mapping->a_ops->truncatepage(page); + /* * We remove the page from the page cache _after_ we have * destroyed all buffer-cache references to it. Otherwise some ---------- Does anyone know who proposed these changes as part of ramfs enhancements? Basically, we have a very similar operation in XFS, but would like the call to truncatepage be _before_ the call to block_flushpage(). As far as ramfs is concerned, such a change would be a no-op since ramfs doesn't have page->buffers. Is this correct?
thanks,
ananth.
