Subject: JFS: Allow security.* xattrs to be set on symlinks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6211502d7ee9e515e4458d0c0ebfbb70553dc7de;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

JFS: Allow security.* xattrs to be set on symlinks

All of the different xattr namespaces have different rules.
user.* and ACL's are not allowed on symlinks, and since these were the
first xattrs implemented, I assumed there was no need to support xattrs
on symlinks.  This one-line patch should fix it.
