I'm not 100% sure but I think something changed in the kernel (i.e. they
added a directory path in the iSCSI target list
*cpus_allowed_list* which rtslib-fb doesn't recognize) that started causing
failure in the rtslib-fb library.
Based on the thread[1], Commit: *d72d827f2f26 ("scsi: target: Add
iscsi/cpus_allowed_list in configfs") *seems
to be causing the issue.
Also looking at the fix in rtslib-fb[2], they are excluding the
directory *"cpus_allowed_list"
*which is failing in our
gate job as Not a directory error.

[Errno 20] Not a directory: \'/sys/kernel/config/target/iscsi/
*cpus_allowed_list*\

Commit message of fix:

target has been added cpus_allowed_list attribute in sysfs.
Therefore, the rtslib should handle the new attribute:
    1. add cpus_allowed_list item in target_names_excludes
    2. add cpus_allowed_list feature in ISCSIFabricModule


This fix is released in rtslib-fb version 2.7.5 and yoga u-c is pinned to
2.7.4.
