[PATCH v3 07/11] rlimits: add rlimit64 structure
Add a platform independent structure for resource limits to use with a new prlimit64 syscall. This structure is the same which uses glibc for 64-bit limits. Also add corresponding infinity which is a 64-bit full of ones. Signed-off-by: Jiri Slaby <jslaby(a)suse.cz> --- include/linux/resource.h | 7 +++++++ ... 10 May 2010 14:19

[PATCH -tip 0/5] kprobes: batch (un)optimization support
Hi, Since current kprobes jump optimization calls stop_machine() for each probe, it will almost freeze machine when registering a lot of probes (~1000) at once. For avoiding this issue, this patch series enhances kprobes and text_poke. - Introduces text_poke_smp_batch() which modifies multiple codes with... 10 May 2010 14:19

[PATCH -tip 2/5] kprobes: Limit maximum number of optimization at once
Since text_poke_smp() uses stop_machine(), the machine almost stop a while if we optimize a lot of probes at once. This patch limits the maximum number of probes to optimize (means calling text_poke_smp()) at once, and try it again after a while if there are more probes waiting for optimization than the limitation... 10 May 2010 14:19

[PATCH -tip 3/5] x86: Introduce text_poke_smp_batch() for batch-code modifying
Introduce text_poke_smp_batch(). This function modifies several text areas with one stop_machine() on SMPr. Because calling stop_machine() is heavy task, it is better to aggregate text_poke requests.

[PATCH] idr: document that idr_for_each may be used under rcu_read_lock()
Hello Nadia, In commit f9c46d6ea5ce138a886c3a0f10a46130afab75f5, you converted idr_find() and idr_for_each() to rcu_dereference(). The documentation of idr_find() was updated to say that it may now be called under rcu_read_lock(). But the doc of idr_for_each() still says: "The caller must serialize idr_for_each(... 10 May 2010 14:19
