Module Name: src
Committed By: rmind
Date: Mon Aug 31 20:48:14 UTC 2009
Modified Files:
src/sys/kern: sys_pipe.c
Log Message:
Turn off pipe's direct I/O again, it corrupts the data (although build and
various activity survived while testing this). Corruptions also happen on
sparc64 where emap is not in effect, therefore bugs are in direct I/O code.
