Subject: blockd: fix length of timeout int passed to ioctl
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=a846c6b98d59b55f1e761ffc5aa75077f6944689;p=project%2Ffstools.git

blockd: fix length of timeout int passed to ioctl

AUTOFS_IOC_SETTIMEOUT expects a pointer to an 'unsigned long' which
will result in out-of-bounds access when passing a pointer to an 'int'.
Change type of timeout to 'unsigned long'.
