From 3cd8a23948b29301f8f67b8d70c5c18fabbc05e1 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 10 Dec 2012 09:26:05 +0900 Subject: f2fs: cleanup the f2fs_bio_alloc routine Do cleanup more for better code readability. - Change the parameter set of f2fs_bio_alloc() This function should allocate a bio only since it is not something like f2fs_bio_init(). Instead, the caller should initialize the allocated bio. - Introduce SECTOR_FROM_BLOCK This macro translates a block address to its sector address.
