Subject: mm/mseal: use min/max in mseal_apply
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7d40e6b66d97d7feef8ca3c096827fd24c6d623d;p=thirdparty%2Flinux.git

mm/mseal: use min/max in mseal_apply

Use the type-checked min()/max() macros instead of MIN()/MAX(), which are
supposed to be used "for obvious constants only".
