From 46e678c96bbd775abd05d3ddbe2fd334794f9157 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sun, 30 Apr 2006 16:36:32 +0200 Subject: [PATCH] splice: fix bugs with stealing regular pipe pages - Check that page has suitable count for stealing in the regular pipes. - pipe_to_file() assumes that the page is locked on succesful steal, so do that in the pipe steal hook - Missing unlock_page() in add_to_page_cache() failure.
