It consists of the following 13 patches: add-atomic-xchg.patch mutex-generic-asm-implementations.patch mutex-asm-mutex.h-i386.patch mutex-asm-mutex.h-x86_64.patch mutex-asm-mutex.h-arm.patch mutex-arch-mutex-h.patch mutex-core.patch mutex-docs.patch mutex-debug.patch mutex-debug-more.patch xfs-use-mutexes.patch vfs-i-sem-to-mutex.patch vfs-use-more-mutexes.patch the patches are against Linus' latest GIT tree, and they should work fine on every Linux architecture. i have tested all 5 mutex implementation variants under MUTEX_DEBUG_FULL on x86: native, -dec, -xchg, -null and debug.
