From 3568a13f4089aac90b3763a2b6c293cd2b638ec1 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Thu, 16 Apr 2015 12:46:34 -0700 Subject: [PATCH] nilfs2: unify type of key arguments in bmap interface The type of key arguments in block mapping interface varies depending on function. For instance, nilfs_bmap_lookup_at_level() takes "__u64" for its key argument whereas nilfs_bmap_lookup() takes "unsigned long". This fits them to "__u64" to eliminate the variation.
