Subject: fd-util: accept that kcmp might fail with EPERM/EACCES
X-Git-Tag: v240~784
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9e2acd1d24a8516c94ce862e9fbf63dd8d751572;p=thirdparty%2Fsystemd.git

fd-util: accept that kcmp might fail with EPERM/EACCES

In a container the kcmp call might well be blocked; Accept that and fall
back to fstat in that case.
