Subject: [PATCH] fat: instead of constant number, use the i_blkbits of struct inode to calculate the number of blocks
Date: Tue, 19 Feb 2013 20:50:38 +0900 [thread overview]
Message-ID: <1361274638-9534-1-git-send-email-hyc.lee@gmail.com> (raw)
To calculate the number of blocks from the number of clusters,
use the i_blkbits of struct inode instead of 9.
