| H A D | iov_iter.c | acbdeb83 Fri Jun 17 12:35:35 CDT 2022 Al Viro <viro@zeniv.linux.org.uk> unify pipe_get_pages() and pipe_get_pages_alloc()
The differences between those two are
* pipe_get_pages() gets a non-NULL struct page ** value pointing to
preallocated array + array size.
* pipe_get_pages_alloc() gets an address of struct page ** variable that
contains NULL, allocates the array and (on success) stores its address in
that variable.
Not hard to combine - always pass struct page ***, have
the previous pipe_get_pages_alloc() caller pass ~0U as cap for
array size.
