[PATCH 4.14 022/185] f2fs: check all the data segments against all node ones

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Surbhi Palande <f2fsnewbie@xxxxxxxxx>

[ Upstream commit 1166c1f2f69117ad254189ca781287afa6e550b6 ]

As a part of the sanity checking while mounting, distinct segment number
assignment to data and node segments is verified. Fixing a small bug in
this verification between node and data segments. We need to check all
the data segments with all the node segments.

Fixes: 042be0f849e5f ("f2fs: fix to do sanity check with current segment number")
