Date: Sun, 10 May 2020 11:54:47 +0530 From: Ritesh Harjani <riteshh@...ux.ibm.com> To: linux-ext4@...r.kernel.org Cc: linux-fsdevel@...r.kernel.org, Jan Kara <jack@...e.com>, tytso@....edu, "Aneesh Kumar K . V" <aneesh.kumar@...ux.ibm.com>, Ritesh Harjani <riteshh@...ux.ibm.com> Subject: [RFC 07/16] ext4: mballoc: Make ext4_mb_use_preallocated() return type as bool Change return type of function ext4_mb_use_preallocated() to bool to better reflect what this function can return. There should be no functionality change in this patch.
