Subject: [PATCH V4 RESEND 3/7] xfs: xfs_attr_calc_size: Calculate Bmbt blks only once
Date: Mon, 24 Feb 2020 09:30:40 +0530 [thread overview]
Message-ID: <20200224040044.30923-4-chandanrlinux@gmail.com> (raw)
In-Reply-To: <20200224040044.30923-1-chandanrlinux@gmail.com>
The number of Bmbt blocks that is required can be calculated only once by
passing the sum of total number of dabtree blocks and remote blocks to
XFS_NEXTENTADD_SPACE_RES() macro.
