From c922bbc819324558e61402a7a76c10c550ca61bc Mon Sep 17 00:00:00 2001 From: Mitsuo Hayasaka Date: Mon, 6 Feb 2012 12:50:30 +0000 Subject: [PATCH] xfs: make inode quota check more general The xfs checks quota when reserving disk blocks and inodes. In the block reservation, it checks if the total number of blocks including current usage and new reservation exceed quota. In the inode reservation, it checks using the total number of inodes including only current usage without new reservation. However, this inode quota check works well since the caller of xfs_trans_dquot() always sets the argument of the number of new inode reservation to 1 or 0 and inode is reserved one by one in current xfs. To make it more general, this patch changes it to the same way as the block quota check.
