Subject: [JFFS2] Don't strip sgid bit from inode permissions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=857013b87b6e0fea776c1f0b365dbce3d6eba8c6;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[JFFS2] Don't strip sgid bit from inode permissions

<viro> dwmw2: anyway, removing sgid from directories or from
       files without S_IXGRP is a plain and simple bug
<viro> these days you don't need that logics at all - simply remove it
