Maybe the wrong list, sorry if so Linux 5.3.18-150300.59.68-preempt [openSUSE Leap 15.3] cifs-utils-6.9-150100.5.15.1.x86_64 As I rebooted with this combination, my CiFS mounts all failed with "Unable to apply new capability set." with or without options, so I could not pin it to a specific option I then rebuilt cifs-utils from git.samba.org/cifs-utils.git 6.15 at 58ca03f183b375cb723097a and all problems were gone. I scanned the git log, but could not point to a specific commit that addressed this issue -- H.Merijn Brand https://tux.nl Perl Monger http://amsterdam.pm.org/ using perl5.00307 .. 5.35 porting perl5 on HP-UX, AIX, and Linux https://tux.nl/email.html http://qa.perl.org https://www.test-smoke.org
