Subject: [PATCH v2 0/3] uprobes: make register/unregister O(n)
Date: Wed, 6 Jun 2012 16:49:33 +0200 [thread overview]
Message-ID: <20120606144933.GA24078@redhat.com> (raw)
In-Reply-To: <20120604145238.GA6408@redhat.com>
Hello,
On top of "[PATCH 0/3] uprobes: misc minor changes".
Sorry for delay. When I tried to test these changes, I hit the
bug report from bad_page(). However, it turns out this is another
unrelated problem, hopefully I'll send the fix soon. In short,
replace_page() is buggy.
Changes:
- do not try GFP_NOWAIT if it failed before and more != 0,
this is pointless and wrong
- update the comments (thanks Peter)
Oleg.
