[PATCH 0/3] Fix some seq_file users that were recently broken

[NeilBrown]

A recent change to seq_file broke some users which were using seq_file
in a non-"standard" way ...  though the "standard" isn't documented, so
they can be excused.  The result is a possible leak - of memory in one
case, of references to a 'transport' in the other.

These three patches:
 1/ document and explain the problem
 2/ fix the problem user in x86
 3/ fix the problem user in net/sctp

I suspect the patches should each go through the relevant subsystems,
but I'm including akpm as the original went through him.

Thanks,
NeilBrown
