Subject: add-vector-aio-support-fix
From: Andrew Morton <akpm@xxxxxxxx>
On sparc32:
fs/read_write.c: In function 'rw_copy_check_uvector':
fs/read_write.c:567: warning: implicit declaration of function 'vrfy_dir'
fs/read_write.c:567: error: 'type' undeclared (first use in this function)
fs/read_write.c:567: error: (Each undeclared identifier is reported only once
fs/read_write.c:567: error: for each function it appears in.)
distcc[26751] ERROR: compile fs/read_write.c on bix/32 failed
This had extensive fallout. Perhaps it'd be better to work out the direction
from the kiocb rather than passing it in.
