From 93407472a21b82f39c955ea7787e5bc7da100642 Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Mon, 27 Feb 2017 14:28:32 -0800 Subject: fs: add i_blocksize() Replace all 1 << inode->i_blkbits and (1 << inode->i_blkbits) in fs branch. This patch also fixes multiple checkpatch warnings: WARNING: Prefer 'unsigned int' to bare use of 'unsigned' Thanks to Andrew Morton for suggesting more appropriate function instead of macro.
