Hi All ,
After I load xeno_psos.ko by "/sbin/insmod xeno_psos.ko", and run my test
program, whic create a queue by "q_vcreate", but not delete it in the test
program. After I finish running my test program. Then I unload the
xeno_psos and then reload it again, it will crash as follow:
/sbin/rmmod xeno_psos
Xenomai: stopping pSOS+ services.
# /sbin/insmod xeno_psos.ko
Xenomai: starting pSOS+ services.
proc_dir_entry 'registry/psos' already registered

The problem is caused by the reason that unloading xeno_psos.ko cannot
clean up the the queues show as follow:
# pwd
/proc/xenomai/registry/psos/queues
# ls
cmq q2r
So can the problem be fixed? Thanks.
Best regards,
Wenyi Gao
