2011-08-10x86-64: Wire up getcpu syscallAndy Lutomirski1-0/+2
getcpu is available as a vdso entry and an emulated vsyscall. Programs that for some reason don't want to use the vdso should still be able to call getcpu without relying on the slow emulated vsyscall. It costs almost nothing to expose it as a real syscall. We also need this for the following patch in vsyscall=native mode.

2011-08-10x86: Remove unnecessary compile flag tweaks for vsyscall codeAndy Lutomirski2-16/+0

2011-08-10"xfs: fix error handling for synchronous writes" revisitedAjeet Yadav1-1/+0
xfs: fix for hang during synchronous buffer write error If removed storage while synchronous buffer write underway, "xfslogd" hangs. Detailed log http://oss.sgi.com/archives/xfs/2011-07/msg00740.html Related work bfc60177f8ab509bc225becbb58f7e53a0e33e81 "xfs: fix error handling for synchronous writes" Given that xfs_bwrite actually does the shutdown already after waiting for the b_iodone completion and given that we actually found that calling xfs_force_shutdown from inside xfs_buf_iodone_callbacks was a major contributor the problem it better to drop this call.

commit 07bd8df5df4369487812bf85a237322ff3569b77 (sch_sfq: fix peek() implementation) changed sfq to use generic peek helper. This makes HFSC complain about a non-work-conserving child qdisc, if prio with sfq child is used within hfsc: hfsc peeks into prio qdisc, which will then peek into sfq. returned skb is stashed in sch->gso_skb. Next, hfsc tries to dequeue from prio, but prio will call sfq dequeue directly, which may return NULL instead of previously peeked-at skb. Have prio call qdisc_dequeue_peeked, so sfq->dequeue() is not called in this case. Cc: Eric Dumazet <[email protected]> Signed-off-by: Florian Westphal <[email protected]> Signed-off-by: David S.

2011-08-09cap_syslog: don't use WARN_ONCE for CAP_SYS_ADMIN deprecation warningJonathan Nieder1-2/+4
syslog-ng versions before 3.3.0beta1 (2011-05-12) assume that CAP_SYS_ADMIN is sufficient to access syslog, so ever since CAP_SYSLOG was introduced (2010-11-25) they have triggered a warning. Commit ee24aebffb75 ("cap_syslog: accept CAP_SYS_ADMIN for now") improved matters a little by making syslog-ng work again, just keeping the WARN_ONCE(). But still, this is a warning that writes a stack trace we don't care about to syslog, sets a taint flag, and alarms sysadmins when nothing worse has happened than use of an old userspace with a recent kernel. Convert the WARN_ONCE to a printk_once to avoid that while continuing to give userspace developers a hint that this is an unwanted backward-compatibility feature and won't be around forever.

2011-08-09slub: Fix partial count comparison confusionChristoph Lameter1-1/+1
deactivate_slab() has the comparison if more than the minimum number of partial pages are in the partial list wrong. An effect of this may be that empty pages are not freed from deactivate_slab(). The result could be an OOM due to growth of the partial slabs per node. Frees mostly occur from __slab_free which is okay so this would only affect use cases where a lot of switching around of per cpu slabs occur. Switching per cpu slabs occurs with high frequency if debugging options are enabled.

The patch adds empty function of_get_property for non-dt build, so that drivers migrating to dt can save some '#ifdef CONFIG_OF'. This also fixes the current Tegra compile problem in linux-next. Signed-off-by: Stephen Warren <[email protected]> Signed-off-by: Grant Likely <[email protected]>
