[PATCH 0/2] cfq-iosched: fixing RQ_NOIDLE handling.
Hi Jens, patch 8e55063 "cfq-iosched: fix corner cases in idling logic", is suspected for some regressions on high end hardware. The two patches from this series: - [PATCH 1/2] cfq-iosched: fix tree-wide handling of rq_noidle - [PATCH 2/2] cfq-iosched: RQ_NOIDLE enabled for SYNC_WORKLOAD fix two issues that I have... 7 Jul 2010 12:22

[PATCH 2/2] cfq-iosched: RQ_NOIDLE enabled for SYNC_WORKLOAD
RQ_NOIDLE flag is meaningful and should be honored for SYNC_WORKLOAD, without further checks. RQ_NOIDLE can be used to mark the last request of a sequence for which - we want to idle between the requests of the sequence, to keep locality - we don't want to idle after the sequence, because we know that no new nea... 7 Jul 2010 12:22

[PATCH 1/2] cfq-iosched: fix tree-wide handling of rq_noidle
Patch: 8e55063 cfq-iosched: fix corner cases in idling logic introduced the possibility of iding even on no-idle requests in the no_idle tree, if any previous request in the current slice could idle. The implementation had a problem, though: - if a queue sent several possibly idling requests and a noidle request... 7 Jul 2010 12:22

ocfs2: When zero extending, do it by page.
Hi Joel, Joel Becker wrote: ocfs2_zero_extend() does its zeroing block by block, but it calls a function named ocfs2_write_zero_page(). Let's have ocfs2_write_zero_page() handle the page level. From ocfs2_zero_extend()'s perspective, it is now page-at-a-time. Signed-off-by: Joel Becker <joel.becker... 8 Jul 2010 06:57

[RFC] perf migration
Hi, To begin with, the name is a bit pompous. It's not a strong cpu task migration observer as it's only based on the number of tasks living in a cpu runqueue. This is the only basis for the cpu load: it doesn't handle the nice level, scheduler classes, of each tasks (except idle ones that don't count on the loa... 7 Jul 2010 12:22

[PATCH 04/10] SELinux: Add new labeling type native labels
There currently doesn't exist a labeling type that is adequate for use with labeled NFS. Since NFS doesn't really support xattrs we can't use the use xattr labeling behavior. For this we developed a new labeling type. The native labeling type is used solely by NFS to ensure NFS inodes are labeled at runtime by the ... 7 Jul 2010 11:15
