-Subject: [PATCH 4/4] LINUX 5.8: use lru_cache_add
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With Linux-5.8-rc1 commit 'mm: fold and remove lru_cache_add_anon() and
-lru_cache_add_file()' (6058eaec), the lru_cache_add_file function is
-removed since it was functionally equivalent to lru_cache_add.
-
-Replace lru_cache_add_file with lru_cache_add.
-
-Introduce a new autoconf test to determine if lru_cache_add is present
-
-For reference, the Linux changes associated with the lru caches:
-
- __pagevec_lru_add introduced before v2.6.12-rc2
-
- lru_cache_add_file introduced in v2.6.28-rc1
- __pagevec_lru_add_file replaces __pagevec_lru_add in v2.6.28-rc1
- vmscan: split LRU lists into anon & file sets (4f98a2fee)
-
- __pagevec_lru_add removed in v5.7 with a note to use lru_cache_add_file
- mm/swap.c: not necessary to export __pagevec_lru_add() (bde07cfc6)
-
- lru_cache_add_file removed in v5.8
- mm: fold and remove lru_cache_add_anon() and lru_cache_add_file()
- (6058eaec)
- lru_cache_add exported
- mm: fold and remove lru_cache_add_anon() and lru_cache_add_file()
- (6058eaec)
-
-Openafs will use:
- lru_cache_add on 5.8 kernels
- lru_cache_add_file from 2.6.28 through 5.7 kernels
- __pagevec_lru_add/__pagevec_lru_add_file on pre 2.6.28 kernels
