Hi all, this series removes most users of the write_one_page API. These helpers internally call ->writepage which we are gradually removing from the kernel. Changes since v2: - more minix error handling fixes Changes since v1: - drop the btrfs changes (queue up in the btrfs tree) - drop the finaly move to jfs (can't be done without the btrfs patches) - fix the existing minix code to

To clarify the issue I posted earlier: I am on OS X 10.6.7. Trying to use Mechanize to log in to LinkedIn. As others have posted about in the past, when I submit the form it kicks me back to the LinkedIn landing page, and does not log me in. I read the earlier discussion of the issue that mentioned how cookie values were being improperly dequoted when stored. But I thought that issue was fixed.

After way to many months here is the fifth version of the guest page hinting patches. Compared to version four a few improvements have been added: - Avoid page_host_discards() calls outside of page-states.h - The discard list is now implemented via the page_free_discarded hook and architecture specific code. - PG_state_change page flag has been replaced with architecture specficic
