[f2fs-dev] [PATCH AUTOSEL 6.1 29/53] f2fs: fix to tag gcing flag on page during block migration

[Sasha Levin <sashal@kernel.org>]

From: Chao Yu <chao@kernel.org>

[ Upstream commit 4961acdd65c956e97c1a000c82d91a8c1cdbe44b ]

It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.

Similar issue was fixed by commit 2d1fe8a86bf5 ("f2fs: fix to tag
gcing flag on page during file defragment").
