Subject: [PATCH] shmem missing cache flush
Date: Wed, 16 Oct 2002 19:26:30 +0100 [thread overview]
Message-ID: <20021016192630.L15163@parcelfarce.linux.theplanet.co.uk> (raw)
Really, this should be a clear_user_page(), but we can't reasonable get
a user address all the way down to it, so let's just flush it instead.
Note that 2.4 needs an equivalent fix.
