Both of these seem a pretty good idea. Should be in version 0.03 which
I'll try and get to Andrew over the weekend. Example reports from files
in 2.6.22-rc2-mm1 below.
-apw
spinlock_t definition without comment
FILE: lib/statistic.c:243:
+ spinlock_t lock;
struct mutex definition without comment
FILE: include/linux/kernelcapi.h:67:
+ struct mutex recv_mtx;
memory barrier without comment
FILE: fs/ext2/balloc.c:1250:
+ smp_rmb();
