[Devel] [RFC PATCH 0/2] autofs: fix autofs_v5_packet dlivery in compat mode

[Stanislav Kinsburskiy]

The problem is that in compat mode struct autofs_v5_packet has to have different size
(i.e. 4 bytes less).

This is RFC because:
1) This issue is hidden, because autofs pipe has O_DIRECT and the rest of the
epacket is truncated when read.
2) X86 arch doesn't have is_compat_task() helper
3) It's now clear, what to do if "pgrp" option is specified.

The following series implements...

      autofs: set compat flag on sbi when daemon uses 32bit addressation
      autofs: sent 32-bit sized packet for 32-bit process
