Subject: [f2fs-dev]  [PATCH] Return valid segment type in 4 head logging
Date: Wed,  7 Aug 2019 13:54:28 -0700	[thread overview]
Message-ID: <20190807205428.3454-1-csurbhi@gmail.com> (raw)

The valid type of current segments in a 4 head logging scheme are:

CURSEG_HOT_DATA, CURSEG_COLD_DATA
CURSEG_HOT_NODE, CURSEG_HOT_NODE.

When a direct node page is not explicitly marked cold,
return CURSEG_HOT_NODE as it's segment type. 
CURSEG_WARM_NODE is not a valid segment type in a
4 head logging scheme.
