Subject: [patch 0/3] Patches in a sake of checkpoint/restore, procfs and prctls
Date: Tue, 13 Dec 2011 00:06:42 +0400 [thread overview]
Message-ID: <20111212200642.836001668@openvz.org> (raw)
Hi,
while /proc/pid/children patch is still under review/rework other
patches were fixed and I hope in good shape. The first one introduces
CONFIG_CHECKPOINT_RESTORE Kconfig symbol which should be a lever to
turn on/off all c/r related features for those who not need it. In
particular new prctl codes are covered by.
Eric pointed that /proc/<pid>/stat enhancement might be a dangerous
one from user-space point of view, so while I've successfuly tested
it, it doesn't mean I've covered every single user-space utility which
might use this file, and if it's still considered to be pretty harmful
change -- I'll hapily move to /proc/pid/statm or whatever. The only
reason it was introduced in "stat" -- we already have mm->start_code
and etc there, so I wanted to have them in one place, not sprinkled
over several files.
Any complains are welcome as usual.
Cyrill
