Hello,
I was looking through some vop_readdir()'s, and noticed an inconsistency
between (at least) xfs and unionfs.
sys/fs/unionfs/union_vnops.c:1410:
if(ap->a_vp->v_type != VDIR)
return (ENOTDIR);
sys/fs/xfs/FreeBSD/xfs_vnops.c:1001:
if(vp->v_type != VDIR)
return (EPERM);
A little userland script gave me a ENOTDIR when trying to
opendir(somefile) (userspace opendir() calling kernelspace readdir()).
So I assume the check is made earlier, but shouldn't the xfs code return
ENOTDIR in this case ?
due to the if-clause above it, you'd say ENOTDIR seems better than EPERM.
