Hello, Looking at kernel/mutex.c and arch/arm/include/asm/mutex.h, it appears there aren't any memory barriers in the fast path of mutexes. I see this was discussed here a long time back: http://patchwork.kernel.org/patch/25856/ How was this resolved? thanks, Steve -- Sent by an employee of the Qualcomm Innovation Center, Inc.
