modinfo -p zfs/spl/zcommon/icp to show default values in a parsable form #11686

Open mailinglists35 opened 3 years ago

Describe the feature would like to see added to OpenZFS

currently the default values are only found in manual pages and only few are shown in the modinfo -p output.

How will this feature improve OpenZFS?

displaying these values in modinfo -p output would make it easy to implement a feature such as #11685 or manually identify altered module parameter values

Additional context

mailinglists35 commented 3 years ago

while looking at modules that have tunable parameters, I found that icp and zcommon do not have manpages for them:

root@zfs:~# modinfo -p zcommon zfs_max_dataset_nesting:Limit to the amount of nesting a path can have. Defaults to 50. (int) zfs_fletcher_4_impl:Select fletcher 4 implementation.

root@zfs:~# modinfo -p icp icp_aes_impl:Select aes implementation. icp_gcm_impl:Select gcm implementation. icp_gcm_avx_chunk_size:How many bytes to process while owning the FPU

root@zfs:~# man icp-module-parameters No manual entry for icp-module-parameters

root@zfs:~# man zcommon-module-parameters No manual entry for zcommon-module-parameters

Yes, sorry. Documenting the ICP module parameters is still on my todo list.
