kstrtoul() exists only after torvalds/linux@33ee3b2e2e in 2.6.39. Use strict_strtoul() if kstrtoul() doesn't exist. Note that strict_strtoul() has existed as an alias for kstrtoul() for a while, but removed in torvalds/linux@3db2e9cdc0. It looks like RHEL6 (2.6.32 based) has backported kstrtoul(), and this caused build CI to pass compilation test. It should fail on vanilla < 2.6.39 kernels or distro kernels without backport as reported in #8760. -- # grep "kstrtoul(" /lib/modules/2.6.32-754.12.1.el6.x86_64/build/ \ include/linux/kernel.h >/dev/null # echo $? 0 Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: loli10K <ezomori.nozomu@gmail.com> Signed-off-by: Tomohiro Kusumi <kusumi.tomohiro@gmail.com> Closes #8760 Closes #8761
