Subject: xfsprogs/mkfs: what's the relationship between max trans res and min log size
Date: Mon, 18 May 2015 14:33:06 +0800	[thread overview]
Message-ID: <555987A2.3050604@foxmail.com> (raw)

Hi guys,


In maxtrres.c/max_trans_res, it calls xfs_log_calc_minimum_size to compute the
              maximum transaction reservation

But for xfs_log_calc_minimum_size, it's used to calculate the
              minimum valid log size


The naming max/minimum seems confusing.

Why are they named in such way? What's the relationship between max trans res
and minimun log size, (max trans res) <= (minimun log size)?


Any explanations are welcomed!


Thanks,
Sheng-Hui
