From ff939afec5548265a80324322838f7a308557579 Mon Sep 17 00:00:00 2001 From: Aditya Garg Date: Wed, 7 Dec 2022 03:05:40 +0000 Subject: [PATCH] hfsplus: fix bug causing custom uid and gid being unable to be assigned with mount commit 9f2b5debc07073e6dfdd774e3594d0224b991927 upstream. Despite specifying UID and GID in mount command, the specified UID and GID were not being assigned. This patch fixes this issue.
