| |
Is there a recommended way to check to see if a slab cache with a specific name exists before calling kmem_cache_create?
I was able to force it into the BUG() at about line 1160 of slab.c by removing my module (rmmod -f) while some of my slab cache objects (e.g. private inode info) were still in use, and then reloading my module which called kmem_cache_create with a name that already existed. I would like to exit module init code with a more graceful error if I could easily detect that my slab cache objects were not deleted (since if I proceed farther in my module init code it will hit the BUG statement on 1160 of slab.c)
Any easy way to check?
