If merge_64() was a standard macro in asm/compat.h on all architectures,
compat_sys_pwrite() could invoke it directly and the need for the compat
wrapper around the compat wrapper would go away.
+1 for this.
AFAIK, there's issues

This patch makes -ru_maxrss value in struct rusage filled accordingly to
rss hiwater mark. This struct is filled as a parameter to
getrusage syscall. -ru_maxrss value is set to pages which might be correct
as time application converts it to KBs.
To make this happen we extend struct signal_struct
Andrew,
I just realized that you weren't cc'd on these when they were posted.
Can we give them a run in -mm? As far as I know, all review comments
have been addressed and there's nothing outstanding.

Btw, this all is an excellent example of why people should try to aim for
small functions and use lots of them.
It's often _way_ more readable to do

Eh? The splitting will occur at the C ABI level, not as a result of

Hmm, if I'm understanding you correctly, adding ref counts explicitly
(like you suggest below) would be used to let a lower layer defer
writes. Seems like this could be just as easily done with explicits
