[PATCH] files: fix preemption issues

2005-09-17T18:50:02+00:00

With the new fdtable locking rules, you have to protect fdtable with either
->file_lock or rcu_read_lock/unlock().  There are some places where we
aren't doing either.  This patch fixes those places.

[PATCH] PR_GET_DUMPABLE returns incorrect info

2005-09-17T18:50:01+00:00

2.6.13 incorporated Alan Cox's patch for /proc/sys/fs/suid_dumpable (one
version of this patch can be found here
http://marc.theaimsgroup.com/?l=linux-kernel&m=109647550421014&w=2 ).

This patch also made corresponding changes in kernel/sys.c to change the
prctl() PR_SET_DUMPABLE operation so that the permitted range of 'arg2' was
modified from 0..1 to 0..2.

However, a corresponding change was not made for PR_GET_DUMPABLE: if the
dumpable flag is non-zero, then PR_GET_DUMPABLE always returns 1, so that
the caller can't determine the true setting of this flag.

[PATCH] Fix spinlock owner debugging

2005-09-13T16:59:04+00:00

fix up the runqueue lock owner only if we truly did a context-switch
with the runqueue lock held. Impacts ia64, mips, sparc64 and arm.

Use the add_taint() interface for setting tainted bit flags instead of
doing it manually.

[PATCH] cpuset semaphore depth check optimize

2005-09-12T16:16:27+00:00

Optimize the deadlock avoidance check on the global cpuset
semaphore cpuset_sem.  Instead of adding a depth counter to the
task struct of each task, rather just two words are enough, one
to store the depth and the other the current cpuset_sem holder.

Thanks to Nikita Danilov for the idea.

[ We may want to change this further, but at least it's now
  a totally internal decision to the cpusets code ]

Mark ia64-specific MCA/INIT scheduler hooks as dangerous

2005-09-12T14:59:21+00:00

..and only enable them for ia64. The functions are only valid
when the whole system has been totally stopped and no scheduler
activity is ongoing on any CPU, and interrupts are globally
disabled.

In other words, they aren't useful for anything else. So make
sure that nobody can use them by mistake.
