JANAK DESAI [Tue, 7 Feb 2006 20:58:58 +0000]
[PATCH] unshare system call -v5: system call handler function

sys_unshare system call handler function accepts the same flags as clone
system call, checks constraints on each of the flags and invokes corresponding
unshare functions to disassociate respective process context if it was being
shared with another task.

Here is the link to a program for testing unshare system call.

http://prdownloads.sourceforge.net/audit/unshare_test.c?download

Please note that because of a problem in rmdir associated with bind mounts and
clone with CLONE_NEWNS, the test fails while trying to remove temporary test
directory.  You can remove that temporary directory by doing rmdir, twice,
from the command line.  The first will fail with EBUSY, but the second will
succeed.  I have reported the problem to Ram Pai and Al Viro with a small
program which reproduces the problem.  Al told us yesterday that he will be
looking at the problem soon.  I have tried multiple rmdirs from the
unshare_test program itself, but for some reason that is not working.  Doing
two rmdirs from command line does seem to remove the directory.

[PATCH] Fix spinlock debugging delays to not time out too early

The spinlock-debug wait-loop was using loops_per_jiffy to detect too long
spinlock waits - but on fast CPUs this led to a way too fast timeout and false
messages.

The fix is to include a __delay(1) call in the loop, to correctly approximate
the intended delay timeout of 1 second.  The code assumes that every
architecture implements __delay(1) to last around 1/(loops_per_jiffy*HZ)
seconds.

[PATCH] mm: compound release fix

Compound pages on SMP systems can now often be freed from pagetables via
the release_pages path.  This uses put_page_testzero which does not handle
compound pages at all.  Releasing constituent pages from process mappings
decrements their count to a large negative number and leaks the reference
at the head page - net result is a memory leak.

The problem was hidden because the debug check in put_page_testzero itself
actually did take compound pages into consideration.

Fix the bug and the debug check.

14 years ago[PATCH] __cmpxchg() must really always be inlined on alpha
Steve Langasek [Tue, 7 Feb 2006 20:58:35 +0000]
[PATCH] __cmpxchg() must really always be inlined on alpha

With the latest 2.6.15 kernel builds for alpha on Debian, we ran into a
problem with undefined references to __cmpxchg_called_with_bad_pointer() in
a couple of kernel modules (xfs.ko and drm.ko; see
http://bugs.debian.org/347556).

It looks like people have been trying to out-clever each other wrt the
definition of "inline" on this architecture :), with the result that
__cmpxchg(), which must be inlined so the compiler can see its argument is
const, is not guaranteed to be inlined.  Indeed, it was not being inlined
when building with -Os.

The attached patch fixes the issue by adding an
__attribute__((always_inline)) explicitly to the definition of __cmpxchg()
instead of relying on redefines of "inline" elsewhere to make this happen.

Ravikiran G Thirumalai [Tue, 7 Feb 2006 20:58:23 +0000]
[PATCH] x86_64: Fix the node cpumask of a cpu going down

Currently, x86_64 and ia64 arches do not clear the corresponding bits in
the node's cpumask when a cpu goes down or cpu bring up is cancelled.  This
is buggy since there are pieces of common code where the cpumask is checked
in the cpu down code path to decide on things (like in the slab down path).
 PPC does the right thing, but x86_64 and ia64 don't (This was the reason
Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce
on other arches).  This patch fixes it for x86_64.  I won't attempt ia64 as
I cannot test it.

Credit for spotting this should go to Alok.

(akpm: this was applied, then reverted.  But it's OK now because we now use
for_each_cpu() in the right places).
