Subject: [PATCH 1/6] afs: Fix afs_launder_page() to set correct start file position
Date: Tue, 24 Aug 2021 14:24:47 +0100 [thread overview]
Message-ID: <162981148752.1901565.3663780601682206026.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <162981147473.1901565.1455657509200944265.stgit@warthog.procyon.org.uk>
Fix afs_launder_page() to set the starting position of the StoreData RPC at
the offset into the page at which the modified data starts instead of at
the beginning of the page (the iov_iter is correctly offset).
The offset got lost during the conversion to passing an iov_iter into
afs_store_data().
Fixes: bd80d8a80e12 ("afs: Use ITER_XARRAY for writing")
