From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jan Kara Subject: [PATCH 0/2 RFC v3] Livelock avoidance for data integrity writeback Date: Fri, 4 Jun 2010 20:40:52 +0200 Message-ID: <1275676854-15461-1-git-send-email-jack@suse.cz> Cc: Andrew Morton , npiggin@suse.de, david@fromorbit.com, linux-mm@kvack.org To: linux-fsdevel@kernel.org Return-path: Sender: owner-linux-mm@kvack.org List-Id: linux-fsdevel.vger.kernel.org Hi, I've revived my patches to implement livelock avoidance for data integrity writes. Due to some concerns whether tagging of pages before writeout cannot be too costly to use for WB_SYNC_NONE mode (where we stop after nr_to_write pages) I've changed the patch to use page tagging only in WB_SYNC_ALL mode where we are sure that we write out all the tagged pages. Later, we can think about using tagging for livelock avoidance for WB_SYNC_NONE mode as well... As always comments are welcome.
