H A D | super.c | 4e4ced93 Wed Apr 01 11:11:25 CDT 2020 Vivek Goyal <vgoyal@redhat.com> dax: Move mandatory ->zero_page_range() check in alloc_dax()
zero_page_range() dax operation is mandatory for dax devices. Right now that check happens in dax_zero_page_range() function. Dan thinks that's too late and its better to do the check earlier in alloc_dax().
I also modified alloc_dax() to return pointer with error code in it in case of failure. Right now it returns NULL and caller assumes failure happened due to -ENOMEM. But with this ->zero_page_range() check, I need to return -EINVAL instead.
