2012-11-27Staging: Android: logger: module_exit implementationLuca Clementi
This patch creates the module_exit for the android logger so that it can be loaded and unloaded as a module. The android logger is already declared as a tristate in the Kconfig but the module_exit function was missing. device_initcall works also with modprobe since include/linux/init.h: #define module_init(x) __initcall(x); ... #define __initcall(fn) device_initcall(fn) Tested against f4a75d2eb7b1e2206094b901be09adb31ba63681 Linux 3.7-rc6 Signed-off-by: Luca Clementi <luca.clementi@gmail.com> Cc: Brian Swetland <swetland@google.com> Cc: Robert Love <rlove@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-05-10staging: android: logger: Allocate logs dynamically at boot (v3)Tim Bird
This changes the log initialization to be dynamic, but still at boot time. These changes are a predecessor to implementing runtime allocation and freeing of logs, to make the Android logger less hard-coded. Change from a fixed set of static log structures, to allocation at init time into a list. Return proper error numbers on log allocation failure.

2012-02-24staging: logger: hold mutex while removing readerRabin Vincent
The readers list is traversed under the log->mutex lock (for example from fix_up_readers()), but the deletion of elements from this list is not being done under this lock.

2012-02-09staging: android: logger: reorder prepare_to_wait and mutex_lockTim Bird

2012-02-09staging: android: logger: simplify and optimize get_entry_lenTim Bird
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.

2011-11-30Revert "Staging: android: delete android drivers"Greg Kroah-Hartman
This reverts commit b0a0ccfad85b3657fe999805df65f5cfe634ab8a. Turns out I was wrong, we want these in the tree. Note, I've disabled the drivers from the build at the moment, so other patches can be applied to fix some build issues due to internal api changes since the code was removed from the tree.
