Wrap all ANDROID config items with a #if to keep from asking if you want specific Android drivers even if you say N to CONFIG_ANDROID Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-06-19Staging: android: binder: fix up some checkpatch warningsGreg Kroah-Hartman
This cleans up the majority of the checkpatch warnings in the android binder driver. All that is left now is a bunch of too-long-line stuff.

2009-06-19Staging: android: lowmemorykiller: fix possible android low memory killer ↵David Rientjes
NULL pointer get_mm_rss() atomically dereferences the actual without checking for a NULL pointer, which is possible since task_lock() is not held.

2009-06-19Staging: android: lowmemorykiller: cleanup android low memory killerDavid Rientjes
Clean up the code in lowmem_shrink() for the Android low memory killer so that it follows the kernel coding style. It's unnecessary to check for p->oomkilladj >= min_adj if the selected task's oomkilladj score is stored since get_mm_rss() will always be greater than zero.

the specified limit by itself From: Arve Hjønnevåg <arve@android.com> This allows processes to be killed when the kernel evict cache pages in an attempt to get more contiguous free memory.

2009-06-19Staging: android: lowmemorykiller: Only iterate over process list when needed.Arve Hjønnevåg
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.

2009-04-17Staging: binder: Defer flush and release operations to avoid deadlocks.Arve Hjønnevåg
If a transaction that contains a file descriptor fails on a later object, the new file descriptor needs to be closed. If this is a binder file descriptor we would deadlock in flush. If there were no other references to the file at this point release would also be called. Signed-off-by: Arve Hjønnevåg <arve@android.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-04-17Staging: binder: Prevent the wrong thread from adding a transaction to the ↵Arve Hjønnevåg

2009-04-17Staging: binder: Keep a reference to the files_struct while the driver is ↵Arve Hjønnevåg
mmapped This prevents breaking fget_light if a single threaded application allows incoming file descriptors (in replies or on nodes). Should also prevent inserting a file in the wrong files_struct if the receving process execs in the middle of a transaction (between task_get_unused_fd_flags and task_fd_install).
