Description Patrick Del Bello 2024-02-24 11:20:38 UTC

With args->args_count == 2 args->args[2] is not defined. Actually the
flags are contained in args->args[1].

Comment 1 Patrick Del Bello 2024-02-24 11:26:12 UTC

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2265814]

This was fixed for Fedora with the 6.6.14 stable kernel updates.
