It currently test to see if errno == -EINVAL and whether the endptr is '\0'. That's not correct however. What we really want it to do is check to see if any error occurred by setting errno to 0 before the conversion. If one did, then try to treat the value as a name. Also fix a bogus compiler warning about cruid being uninitialized. Signed-off-by: Jeff Layton <jlayton@samba.org> --- mount.cifs.c | 11 +++++++---- 1 files changed, 7 insertions(+), 4 deletions(-)
