--- Comment #1 from Chao Yu ([email protected]) ---
I didn't see many filesystems are using kzfree(), instead, there are many
callers come from crypto module, I guess they use the buffer to store
ciphertext or crypto key temporarily, so, before freeing those buffer it will
be better to clean the data in buffer to avoid confidential data leak.

For f2fs, I think there is no such demand, and we just missed to change kzfree
to kvfree in below commit:

5222595d093e ("f2fs: use kvmalloc, if kmalloc is failed")
