Subject: [PATCH v2 0/1] perf mem: improves DSO long names search speed with RB tree
Date: Tue, 16 Sep 2014 15:08:18 -0400 [thread overview]
Message-ID: <1410894499-27609-1-git-send-email-Waiman.Long@hp.com> (raw)
v1->v2:
- Rename DSO longname RBtree find function to segregate its two different
uses of searching and linking DSO into RB tree.
This patch addes a RBtree to sort the DSO structures of the perf tool
by its long name so that searching for a match will be much quicker
especially if a large number of DSOs are beining profiled.
