Subject: iomap: fix page_done callback for short writes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=36a7347de097edf9c4d7203d09fa223c86479674;p=linux.git

iomap: fix page_done callback for short writes

When we truncate a short write to have it retried, pass the truncated
length to the page_done callback instead of the full length.
