Re: [PATCH v4 1/2] KVM: guest_memfd: add generic population via write

write syscall populates guest_memfd with user-supplied data in a generic way, ie no vendor-specific preparation is performed. This is supposed to be used in non-CoCo setups where guest memory is not hardware-encrypted.

The following behaviour is implemented:

• only page-aligned count and offset are allowed
• if the memory is already allocated, the call will successfully populate it
• if the memory is not allocated, the call will both allocate and populate
• if the memory is already populated, the call will not repopulate it

Just nothing that checkpatch complains about

a) Usage of "unsigned" instead of "unsigned int"

b) The From doesn't completely match the SOB: "Kalyazin, Nikita" vs "Nikita Kalyazin"
