Subject: hfsplus: fix getxattr return value
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=46bf36ecec79bbe5373ef68f0ed36cbf62e03482;p=openwrt%2Fstaging%2Fblogic.git

hfsplus: fix getxattr return value

We need to support -EOPNOTSUPP for attributes that are not supported to
match other filesystems and allow userspace to detect if Posix ACLs
are supported or not.  setxattr already gets this right.
