Subject: [PATCH 03/11] drm/amdgpu: convert amdgpu_vm_it to half closed intervals
Date: Thu, 3 Oct 2019 13:18:50 -0700 [thread overview]
Message-ID: <20191003201858.11666-4-dave@stgolabs.net> (raw)
In-Reply-To: <20191003201858.11666-1-dave@stgolabs.net>
The amdgpu_vm interval tree really wants [a, b) intervals,
not fully closed ones. As such convert it to use the new
interval_tree_gen.h, and also rename the 'last' endpoint
in the node to 'end', which is both a more suitable name
for the half closed interval and also reduces the chances
of missing a conversion when doing insertion or lookup.
