Subject[PATCH 0/3] Reduce mmap_sem usage for args manipulation
Date
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
