Subject: [PATCH 0/3] Reduce mmap_sem usage for args manipulation
Date: Tue, 30 Apr 2019 10:18:41 +0200 [thread overview]
Message-ID: <20190430081844.22597-1-mkoutny@suse.com> (raw)
In-Reply-To: <20190418182321.GJ3040@uranus.lan>
Hello.
(apologies for late reply) I've aggregated the two previously discussed patches
into one series and based on responses made some changes summed below.
v2
- insert a patch refactoring validate_prctl_map
- move find_vma out of the arg_lock critical section
Michal Koutný (3):
mm: get_cmdline use arg_lock instead of mmap_sem
prctl_set_mm: Refactor checks from validate_prctl_map
prctl_set_mm: downgrade mmap_sem to read lock
