[PATCH v4 0/2] lib/raid: replace __get_free_pages() call with kvmalloc()

Posted by Mike Rapoport (Microsoft) 1 week, 4 days ago

This is a (tiny) part of larger work of replacing page allocator calls
with k*malloc.

Nowadays the right way to say "I need a buffer" is kmalloc() rather than
ancient and ugly __get_free_pages().

I'll rewrite this to "... kmalloc()"
