62dfb5541 [PATCH] session_of_pgrp: kill unnecessary do_each_task_pid(PIDTYPE_PGID) ... Browse Code »

All members of the process group have the same sid and it can't be == 0.

NOTE: this code (and a similar one in sys_setpgid) was needed because it
was possibe to have ->session == 0. It's not possible any longer since

All tasks in the process group have the same sid, we don't need to iterate
them all to check that the caller of sys_setpgid() doesn't change its

84d737866 [PATCH] add child reaper to pid_namespace ... Browse Code »

Add a per pid_namespace child-reaper. This is needed so processes are reaped
within the same pid space and do not spill over to the parent pid space. Its
also needed so containers preserve existing semantic that pid == 1 would reap
orphaned children.

This is based on Eric Biederman's patch: http://lkml.org/lkml/2006/2/6/285

9a575a92d [PATCH] to nsproxy ... Browse Code »

Add the pid namespace framework to the nsproxy object. The copy of the pid
namespace only increases the refcount on the global pid namespace,
init_pid_ns, and unshare is not implemented.

There is no configuration option to activate or deactivate this feature
because this not relevant for the moment.

f0d1b0b30 [PATCH] LOG2: Implement a general integer log2 facility in the kernel ... Browse Code »

This facility provides three entry points:

ilog2() Log base 2 of unsigned long
ilog2_u32() Log base 2 of u32
ilog2_u64() Log base 2 of u64

These facilities can either be used inside functions on dynamic data:

int do_something(long q)
{
...;
y = ilog2(x)
...;
}

Or can be used to statically initialise global variables with constant values:

unsigned n = ilog2(27);

When performing static initialisation, the compiler will report "error:
initializer element is not constant" if asked to take a log of zero or of
something not reducible to a constant. They treat negative numbers as
unsigned.

When not dealing with a constant, they fall back to using fls() which permits
them to use arch-specific log calculation instructions - such as BSR on
x86/x86_64 or SCAN on FRV - if available.
