[PATCH 9/9] perf annotate: Sort by hottest lines in the TUI
From: Arnaldo Carvalho de Melo <acme(a)redhat.com> Right now it will just sort and position at the hottest line, i.e. the one where more samples were taken. It will be at the center of the screen and later TAB/shift-TAB will cycle thru the hottest lines. Cc: Frederic Weisbecker <fweisbec(a)gmail.com> Cc: Mike G... 10 Aug 2010 16:55

[PATCH 6/9] perf symbols: Ignore mapping symbols on ARM
From: Dave Martin <dave.martin(a)linaro.org> ARM ELF files use symbols with special names $a, $t, $d to identify regions of ARM code, Thumb code and data within code sections. This can cause confusing output from the perf tools, especially for partially stripped binaries, or binaries containing user-added zero-siz... 10 Aug 2010 16:55

Why is get_user_pages so slow?
Hi all, Why is get_user_pages much slower than taking the faults? (I would expect it to be faster). Attached example program first mallocs a piece of memory (64MB in this case) then reads it "to take the faults". Afterwards, it uses mmap with MAP_POPULATE to "speed up" and not to have to take the faults, bu... 12 Aug 2010 07:06

[PATCH] cgroup_freezer: Freezing and task move race fix
Writing 'FROZEN' to freezer.state file does not forbid the task to be moved away from its cgroup (for a very short time). Nevertheless the moved task can become frozen OUTSIDE its cgroup which puts discussed task in a permanent 'D' state. This patch forbids migration of either FROZEN or FREEZING tasks. This ... 10 Aug 2010 16:55
