From 085d2a3dd4d65b7bce1dead987c647dbbc014281 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 11 Nov 2013 18:20:51 -0800 Subject: bcache: Make bch_keylist_realloc() take u64s, not nptrs Getting away from KEY_PTRS and moving toward KEY_U64s - and getting rid of magic 2s Also - split out the part that checks against journal entry size so as to avoid a dependancy on struct cache_set in bset.c Signed-off-by: Kent Overstreet --- drivers/md/bcache/bset.c | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) (limited to 'drivers/md/bcache/bset.c') diff --git a/drivers/md/bcache/bset.c b/drivers/md/bcache/bset.c index e688265..f91347a 100644 --- a/drivers/md/bcache/bset.c +++ b/drivers/md/bcache/bset.c @@ -14,21 +14,13 @@ /* Keylists */ -int bch_keylist_realloc(struct keylist *l, int nptrs, struct cache_set *c) +int __bch_keylist_realloc(struct keylist *l, unsigned u64s) { size_t oldsize = bch_keylist_nkeys(l); - size_t newsize = oldsize + 2 + nptrs; + size_t newsize = oldsize + u64s; uint64_t *old_keys = l->keys_p == l->inline_keys ?
