For this record this was committed to Linus' tree as 00a926422765064cb28e218d4837411c88bf6a3e http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=00a926422765064cb28e218d4837411c88bf6a3e I believe it made it into 2.6.13, and thus should now be in experimental and make it into unstable (sid) and testing (etch) shortly. I took a look into backporting it to 2.6.8, however, it seems to rely on some restructuring of shared nfs_page data, which can be found as 6caf69feb23a522921b5b12f572a94334183bc9f in the tglx history tree. http://www.kernel.org/git/?p=linux/kernel/git/tglx/history.git;a=commit;h=6caf69feb23a522921b5b12f572a94334183bc9f Unfortunatley, even a minimal backport seems to require changing nfs_page, which would alter the ABI, which is higly probematic. Because of this I am going to mark it as wontfix for 2.6.8. For anyone who wants to make the backport, my idea is to make a minimal nfs_open_context that only includes dir_pos and dir_cookie, the two elements added by the patch Trond posted (6caf69feb23a522921b5b12f572a94334183bc9f). This should cut down the complexity of the backport of the second patch while maintaining the functionality of the first. -- Horms -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
