Subject: [PATCH V4 3/7] xfs: xfs_attr_calc_size: Calculate Bmbt blks only once
Date: Sun, 23 Feb 2020 13:00:40 +0530 [thread overview]
Message-ID: <20200223073044.14215-3-chandanrlinux@gmail.com> (raw)
In-Reply-To: <20200223073044.14215-1-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.
