-MIME-Version: 1.0
-Content-Type: text/plain; charset=utf-8
-Content-Transfer-Encoding: 8bit
-
-Use NR_ACTIVE plus NR_INACTIVE as a size estimate for our fake cache
-instead the sum of rss. Neither method is accurate.
-
-Also skip the process scan, if the amount of memory available is above
-the largest threshold set.

-Subject: [PATCH 056/134] mm: Check if any page in a pageblock is reserved before marking it MIGRATE_RESERVE
-
-This fixes a problem where the first pageblock got marked MIGRATE_RESERVE even
-though it only had a few free pages. This in turn caused no contiguous memory
-to be reserved and frequent kswapd wakeups that emptied the caches to get more
-contiguous memory.

-If EARLYSUSPEND is enabled then writes to /sys/power/state no longer
-blocks, and the kernel will try to enter the requested state every
-time no wakelocks are held. Write "on" to resume normal operation.

-Subject: [PATCH 069/134] PM: Add user-space wake lock api.
-
-This adds /sys/power/wake_lock and /sys/power/wake_unlock.
-Writing a string to wake_lock creates a wake lock the
-first time is sees a string and locks it. Optionally, the
-string can be followed by a timeout.
-To unlock the wake lock, write the same string to wake_unlock.

-Rather than signaling a full update of the display from userspace via a
-console switch, this patch introduces 2 files int /sys/power,
-wait_for_fb_sleep and wait_for_fb_wake. Reading these files will block
-until the requested state has been entered. When a read from
-wait_for_fb_sleep returns userspace should stop drawing. When
-wait_for_fb_wake returns, it should do a full update. If either are called
-when the fb driver is already in the requested state, they will return
-immediately.

-Introduce a new socket ioctl, SIOCKILLADDR, that nukes all sockets

-Subject: [PATCH 082/134] sysfs_net_ipv4: Add sysfs-based knobs for controlling TCP window size
-
-Add a family of knobs to /sys/kernel/ipv4 for controlling the TCP window size:
-
- tcp_wmem_min
- tcp_wmem_def
- tcp_wmem_max
- tcp_rmem_min
- tcp_rmem_def
- tcp_rmem_max
-
-This six values mirror the sysctl knobs in /proc/sys/net/ipv4/tcp_wmem and
-/proc/sys/net/ipv4/tcp_rmem.
-
-Sysfs, unlike sysctl, allows us to set and manage the files' permissions and
-owners.

-
- With this feature enabled, mmcblk will check the card-status before issuing
-a transaction *only* after being resumed. This protectes us from issuing
-transactions before the sdcard is ready (which can occur if the host driver
-deferrs mmc_resume_host() to reduce resume latency)

-Subject: [PATCH 129/134] [ARM] goldfish: qemutrace: Kernel instrumentation for tracing the events.
-
-Like fork, context switch, execve and exit.
-This code is to complement Jack's tracing facility.
-
-To turn tracing on:
-echo 1 > /sysfs/qemu_trace/state
-To turn tracing off: echo 0 > /sysfs/qemu_trace/state
-I also added java methods to Debug.java to turn tracing on and off.
-The kernel driver also supports adding dynamic symbols to the trace.
-To add a symbol 'foo' with hex address 'abcd1234' to the trace:
-echo 'abcd1234 foo' > /sysfs/qemu_trace/symbol
-
-Signed-off-by: Mike Chan <mike@android.com>
-
-[ARM] goldfish: qemutrace: Improved support for tracing thread and process names.
-
-Added a new pseudo file /sys/qemu_trace/process_name to allow user
-programs to add a trace record for a process name change. Removed
-the tracing of thread and process names from the exit() system call
-because that was not sufficiently general. Added tracing of thread
-names in set_task_comm() and daemonize(). Added tracing of the
-thread group id to fork() and clone().
