Subject: [PATCH] Ignore unbootable kernels in /lib/modules
|
|
|
|
The previous commit didn't ignore zfcpdump kernels if found in
|
|
/lib/modules because we didn't apply the kernel filter to those paths.
|
|
|
|
Also this commit cleans up the code in general, splitting up the
|
|
multi-purpose "kernel_filter" function into two parts with clearer
|
|
roles.
|
|
|
|
Fixes: commit 9fbe476d4df0b01568d3668e6121cae7c779c8c7
|
|
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2027375
