The patch-queue consists of 21 patches, which can also be downloaded from: http://redhat.com/~mingo/generic-mutex-subsystem/ Changes since -V13: 13 files changed, 113 insertions(+), 85 deletions(-) - VFS: converted sb->s_lock to a mutex too. This improves the create+unlink benchmark on ext3. - further simplification of __mutex_lock_common(): no more gotos, and only one atomic_xchg() is done. Code size is now extremely small on both UP and SMP: text data bss dec hex filename 398 0 0 398 18e mutex.o.UP text data bss dec hex filename 463 0 0 463 1cf mutex.o.SMP - synchro-test updates: max # of threads of 64, fairness stats, better defaults if =y, cleanups. (David Howells, me) - FASTCALL -> fastcall in mutex.h (suggested by David Howells) - documentation updates Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
