The patch titled
AFS: further write support fixes
has been removed from the -mm tree. Its filename was
afs-further-write-support-fixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: AFS: further write support fixes
From: David Howells <dhowells@xxxxxxxxxx>
Further fixes for AFS write support:
(1) The afs_send_pages() outer loop must do an extra iteration if it ends
with 'first == last' because 'last' is inclusive in the page set
otherwise it fails to send the last page and complete the RxRPC op under
some circumstances.
(2) Similarly, the outer loop in afs_pages_written_back() must also do an
extra iteration if it ends with 'first == last', otherwise it fails to
clear PG_writeback on the last page under some circumstances.
