Several fixes for Nick's RCU stuff; open() without O_CREAT
can be tricked into creating files, ->d_compare() in /proc/sys is trying
and failing to be RCU-safe (strictly speaking not a regression, but only
because it will be kicked out of RCU mode by ->permission() refusing
to accept IPERM_FLAG_RCU) and spurious errors in open() and vfs_path_lookup()
since we forget to set nd->inode on the LOOKUP_REVAL attempt. More fixes
tomorrow... Please, pull from

Shortlog:
Al Viro (3):
minimal fix for do_filp_open() race
unfuck proc_sysctl ->d_compare()
nd->inode is not set on the second attempt in path_walk()
