staging: ramster: cluster/messaging foundation · 1135ca9c

由 Dan Magenheimer 提交于 1月 30, 2012

Copy cluster subdirectory from ocfs2.  These files implement
the basic cluster discovery, mapping, heartbeat / keepalive, and
messaging ("o2net") that ramster requires for internode communication.
Note: there are NO ramster-specific changes yet; this commit
does NOT pass checkpatch since the copied source files do not.

(Why copy?  This particular part of ocfs2 has never been broken out
for non-ocfs2 use before, some (small) changes are required for ramster
to use that code, and ramster is currently incompatible with real
ocfs2 anyway (requires !CONFIG_OCFS2_FS).  Before ramster can be promoted
out of staging, we will need to work with the ocfs2 maintainers to
see if the code interdependencies can be merged, but for now, for
staging, this seemed to be an expedient way to make use of the ocfs2
core cluster code while still incorporating necessary changes for ramster.)

staging: android/lowmemorykiller: Better mm handling · 95670001

由 Anton Vorontsov 提交于 2月 06, 2012

LMK should not directly check for task->mm. The reason is that the
process' threads may exit or detach its mm via use_mm(), but other
threads may still have a valid mm. To catch this we use
find_lock_task_mm(), which walks up all threads and returns an
appropriate task (with lock held).

staging: android/lowmemorykiller: Don't grab tasklist_lock · 294b2711

由 Anton Vorontsov 提交于 2月 06, 2012

Grabbing tasklist_lock has its disadvantages, i.e. it blocks
process creation and destruction. If there are lots of processes,
blocking doesn't sound as a great idea.

For LMK, it is sufficient to surround tasks list traverse with
rcu_read_{,un}lock().

>From now on using force_sig() is not safe, as it can race with an
already exiting task, so we use send_sig() now. As a downside, it
won't kill PID namespace init processes, but that's not what we
want anyway.

staging: android: logger: simplify and optimize get_entry_len · 3bcfa431

由 Tim Bird 提交于 2月 08, 2012

Make this code slightly easier to read, and eliminate calls
to sub-routines.  Some of these were previously optimized away
by the compiler, but one memcpy was not.

In my testing, this makes the code about 20% smaller, and
has no sub-routine calls and no branches (on ARM).

v2 of this patch is, IMHO, easier to read than v1. Compared to
that patch it uses __u8 instead of unsigned char, for
consistency with the __u16 val data type, simplifies the
conditional expression, adds a another comment, and
moves a common statement out of the if.
