bsdacct: rename acct_gbls to bsd_acct_struct
...
After I fixed access to task->tgid in kernel/acct.c, Oleg pointed out some
bad side effects with this accounting vs pid namespaces interaction. I.e.
when some task in pid namespace sets this accounting up, this blocks all
the others from doing the same. Restricting this to init namespace only
could help, but didn't look a graceful solution.
So here is the approach to make this accounting work with pid namespaces
properly.
The idea is simple - when a task dies it accounts itself in each namespace
it is visible from and which set the accounting up.
For example here are the commands run and the output of lastcomm from init
and sub namespaces:
init_ns# accton pacct
sub_ns# accton pacct (this is a different file - sub ns is run in
a chroot-ed environment)
init_ns# cat /dev/null
sub_ns# ls /dev/null
init_ns# accton
sub_ns# accton
sub_ns# lastcomm -f pacct
ls 0 [136,0] 0.00 secs Thu May 15 10:30
accton 0 [136,0] 0.00 secs Thu May 15 10:30
init_ns# lastcomm -f pacct
accton root pts/0 0.00 secs Thu May 15 14:30 << got from sub
cat root pts/1 0.00 secs Thu May 15 14:30
ls root pts/0 0.00 secs Thu May 15 14:30 << got from sub
accton root pts/1 0.00 secs Thu May 15 14:30
That was the summary, the details are in patches.
This patch:
It will be visible in pid_namespace.h file, so fix its name to look better
outside the acct.c file.
