The first 4 patches add BKL lock into umount_begin() functions (for the filesystems that have this handler). The last one remove lock_kernel()/unlock_kernel() from fs/namespace.c (the only point that invoke umount_begin() funtcions). -- 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/
