Subject: um: Hard-code the result of 'uname -s'
X-Git-Tag: v6.6.7~1985^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d32df1080f0199f3570a541fcfcf9b5974b771db;p=platform%2Fkernel%2Flinux-starfive.git

um: Hard-code the result of 'uname -s'

We rely on 'uname -s' returning 'Linux' because there are os-Linux/
directories, but no other os-*/.

Supporting a non-Linux host is unlikely to happen.

Let's hard-code 'Linux'.
