[PATCH 1/2] QUOTA cleanup: Use inode->i_blkbits to get block bits

[Mingming Cao <cmm@xxxxxxxxxx>]

quota: Use inode->i_blkbits to get block bits

From: Mingming Cao <cmm@xxxxxxxxxx>

Andrew has suggested to use inode->i_blkbits to get the block bits info,
rather than use super block's blockbits. That should be faster and emit
less code.
