Dear All, Need your assistance: Currently I am using Wind River Linux distribution OS with kernel version 2.6.27.39 and Wind River version pne-3. After loading of my kernel module, I found it was permanent in the kernel using lsmod (for ex see below Ref 1). When I tried to remove, it was displaying as “ERROR: Removing 'hsl_module': Device or resource busy”. For your information, the same module is working fine with the Wind River pne-2 Linux Distribution OS with kernel version 2.6.21. >From the kernel source, I came to know that only possibility of showing permanent is “if there is non-availability of cleanup_module and with the availability of init_module”. But in my case, cleanup module also available in memory, after loading the module. I used to check using the file in /proc/kallsyms for the availability of cleanup module in memory. Thanks for reading. Prompt reply is expected to identify the root cause. Ref 1: Module Size Used by hsl_module 530454 0 [permanent] Thanks, Sakthi Selvam _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
