LINUX-5.7: replace __pagevec_lru_add with lru_cache_add_file
The Linux function __pagevec_lru_add is no longer exported in Linux
5.7-rc1 commit
bde07cfc65da5fe6c63fe23f035f5ccc0ffd89e0
"mm/swap.c: not necessary to export __pagevec_lru_add()".
As a replacement, the Linux function lru_cache_add_file can be used for
adding a page to the lru cache. The internal processing of
lru_cache_add_file manages its own internal pagevec and performs the
following:
get_page(...)
if(!pagevec_add(...))
__pagevec_lru_add_file(...)
Introduce an autoconf test for lru_cache_add_file and replace the calls
associated with __pagevec_lru_add with lru_cache_add_file.
NOTE: see Linux commit
a0b8cab3b9b2efadabdcff264c450ca515e2619c
"mm: remove lru parameter from __pagevec_lru_add and remove parts of
pagevec API" as a reference for this change.
The lru_cache_add_file was introduced in Linux 2.6.28, therefore this
change affects systems with Linux 2.6.28 kernels and later.
