Despite several examples in the kernel, the third argument ofsysctl_handle_int is not sizeof the int type you want to export.The type must always be an int or an unsigned int.Remove the instances where a sizeof(variable) is passed to stoppeople accidently cut and pasting these examples.In a few places this was sysctl_handle_int was being used on 64 bittypes, which would truncate the value to be exported. In thesecases use sysctl_handle_quad to export them and change the formatto Q so that sysctl(1) can still print them.

A GEOM cache can speed up read performance by sending fixed sizeread requests to its consumer. It has been developed to addressthe problem of a horrible read performance of a 64k blocksize FSresiding on a RAID3 array with 8 data components, where a singledisk component would only get 8k read requests, thus effectivelykilling disk performance under high load. Documentation will beprovided later. I'd like to thank Vsevolod Lobko for his brightideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.
