Good idea! Sort out some NFS pain.
If a filesystem doesn't honour AT_STRICT, can we have the function
return an error instead of stale values?
I think AT_SYNC, AT_UPTODATE, AT_CURRENT or AT_NOW are clearer names
than AT_STRICT, but it doesn't matter.
Actually, all the names with AT_ are a bit silly, just because it
happens to use the same flag space at the *at() syscalls. They don't
have anything to do with "atness". What about calling these flags
STAT_*?
