Subject: AFS: Fix afs_prepare_write()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bb33ed6345d6156484f39089aa8b52f44ce76609;p=deliverable%2Flinux.git

AFS: Fix afs_prepare_write()

afs_prepare_write() should not mark a page up to date if it only partially
fills it in, in expectation of the caller filling in the rest prior to calling
commit_write().  commit_write(), however, should mark the page up to date.
