X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a17164e54bf0e3c2cbc72c35b9f67c2873a122dd;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

fs/xfs remove obsolete simple_strto<foo>

This patch replaces usages of obsolete simple_strtoul with kstrtoint in
xfs_args and suffix_strtoul.
