Subject: Re: [PATCH 3/4] VFS: factor out three helpers for FIBMAP/FIONBIO/FIOASYNC file ioctls 

BTW, what's the origin of this oddity in fs/ioctl.c:

#ifdef __sparc__
	/* SunOS compatibility item. */
	if (O_NONBLOCK != O_NDELAY)
		flag |= O_NDELAY;
#endif

It seems rather odd to have architecture-specific code in the VFS, no?

Erez.
