[PATCH] docs: clean up and add rest of CRC functions to kernel-api.rst

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Add the rest of the CRC library functions to kernel-api.

- try to clarify crc32() by adding '@' to a function parameter
- reorder kernel-api CRC functions to be less random
- add more CRC functions to kernel-api
- correct the function parameter names in several places

Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
