Since the ION patchset landed in staging-next, there have been a few build issue reports, and this patchset tries to address them.
Dropped the RFC, as I think the first two are good to go, but I'd still like to get acks from Colin or someone else on the Android team on all of these before merging these, as some bits were a bit more complex then I'd like. Changes in v2: o Fixed up style issue Greg caught o Reworked second patch to simplify error path and just return null if kmalloc fails o Per Colin's suggestion, reworked third patch to use spinlocks. This ended up being a bit more complicated to get right, and I'd appreciate very close review, but it seems to be working ok in testing on both ARM and x86_64 w/o triggering any lockdep or other warnings. I'd appreciate any thoughts or comments! thanks -john Cc: Colin Cross <ccr...@android.com> Cc: Android Kernel Team <kernel-t...@android.com> Cc: Greg KH <gre...@linuxfoundation.org> John Stultz (3): staging: ion: Add HAVE_MEMBLOCK config dependency staging: ion: Fix possible null pointer dereference staging: ion: Avoid using rt_mutexes directly. drivers/staging/android/ion/Kconfig | 1 + drivers/staging/android/ion/ion_heap.c | 31 ++++++++++++++++----------- drivers/staging/android/ion/ion_priv.h | 2 +- drivers/staging/android/ion/ion_system_heap.c | 7 +++++- 4 files changed, 27 insertions(+), 14 deletions(-) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
