Nilay Shroff 84909f7dec nvmet: use kzalloc instead of ZERO_PAGE in nvme_execute_identify_ns_nvm() ... The nvme_execute_identify_ns_nvm function uses ZERO_PAGE for copying SG list with all zeros. As ZERO_PAGE would not necessarily return the virtual-address of the zero page, we need to first convert the page address to kernel virtual-address and then use it as source address for copying the data to SG list with all zeros. Using return address of ZERO_PAGE(0) as source address for copying data to SG list would fill the target buffer with random/garbage value and causes the undesired side effect. As other identify implemenations uses kzalloc for allocating a zero filled buffer, we decided use kzalloc for allocating a zero filled buffer in nvme_execute_identify_ns_nvm function and then use this buffer for copying all zeros to SG list buffers. So esentially, we now avoid using ZERO_PAGE.
