Subject: [PATCH 0/7] uprobes: kill uprobes_state->count, add MMF_HAS_UPROBES
Date: Wed, 8 Aug 2012 19:36:59 +0200	[thread overview]
Message-ID: <20120808173659.GA13220@redhat.com> (raw)

Hello.

Srikar, please review.

This is the first part. The next series will teach uprobes to
clear MMF_HAS_UPROBES, but perhaps we should simply remove
uprobe_munmap() instead. A wrong MMF_HAS_UPROBES doesn't hurt
unless the task hits the non-uprobe "int3", not sure it really
makes sense to try to speedup this case. We will see.

7/7 is offtopic.

Oleg.
