Modified files:
sys/kern kern_descrip.c vfs_aio.c vfs_syscalls.c
sys/posix4 posix4_mib.c
sys/sys vnode.h
Log:
Change the way support for asynchronous I/O is indicated to applications
to conform to 1003.1-2001. Make it possible for applications to actually
tell whether or not asynchronous I/O is supported.
Since FreeBSD's aio implementation works on all descriptor types, don't
call down into file or vnode ops when [f]pathconf() is asked about
_PC_ASYNC_IO; this avoids the need for every file and vnode op to know about
it.
