Subject: [PATCH V21 04/19] Btrfs: Remove extent_io_tree's track_uptodate member
Date: Sun,  2 Oct 2016 18:54:13 +0530	[thread overview]
Message-ID: <1475414668-25954-5-git-send-email-chandan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1475414668-25954-1-git-send-email-chandan@linux.vnet.ibm.com>

We now track block uptodate status using a page's PG_Uptodate
flag. Hence this commit removes the now unused
extent_io_tree->track_uptodate member.
