From 0d51be591f3b56b4e3c83f4ca09b61ad33c76b69 Mon Sep 17 00:00:00 2001 From: Andrew Morton <akpm@digeo.com> Date: Tue, 18 Feb 2003 05:24:42 -0800 Subject: [PATCH] [PATCH] export add_to_page_cache() and __pagevec_lru_add to CIFS is using these. Given that the readpages() address_space op is supposed to add the pages to pagecache, it makes sense to make these functions available to modules. I can't say that I put a lot of though into the readpages API. It was designed as just enough functionality to be able to stuff a bunch of readahead pages into a single BIO. The only reason I made it an a_op at all was because we have toi enter the fs to pick up the ->get_block callback's address. But a couple of filesystems seem to be making use of it now. Reiser4 will need access at the do_page_cache_readahead() level too. --- kernel/ksyms.c | 2 ++ mm/filemap.c | 1 + 2 files changed, 3 insertions(+) diff --git a/kernel/ksyms.c b/kernel/ksyms.c index f0503df9fe3d..f30934957b82 100644 --- a/kernel/ksyms.c +++ b/kernel/ksyms.c @@ -31,6 +31,7 @@ #include <linux/genhd.h> #include <linux/blkpg.h> #include <linux/swap.h> +#include <linux/pagevec.h> #include <linux/ctype.h> #include <linux/file.h> #include <linux/console.h> @@ -80,6 +81,7 @@ EXPORT_SYMBOL(__alloc_pages); EXPORT_SYMBOL(__get_free_pages); EXPORT_SYMBOL(get_zeroed_page); EXPORT_SYMBOL(__page_cache_release); +EXPORT_SYMBOL(__pagevec_lru_add); EXPORT_SYMBOL(__free_pages); EXPORT_SYMBOL(free_pages); EXPORT_SYMBOL(num_physpages); diff --git a/mm/filemap.c b/mm/filemap.c index 80be4e6d869c..f6009bff7467 100644 --- a/mm/filemap.c +++ b/mm/filemap.c @@ -225,6 +225,7 @@ int add_to_page_cache(struct page *page, struct address_space *mapping, } return error; } +EXPORT_SYMBOL(add_to_page_cache); int add_to_page_cache_lru(struct page *page, struct address_space *mapping, pgoff_t offset, int gfp_mask) -- 2.30.9
