but everytime we dive into crget() we are taking a mutex and grabbing an entry from the pool. that's essentially what kmalloc does most of the time anyway. you could save a little bit of memory not keeping track of the same buffers twice. i suspect empirical testing would be necessary to decide if there is any perceptable difference. _______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
