Subject: [PATCH] ovl: fix incorrect extent info in metacopy case
Date: Wed, 24 Jun 2020 18:20:11 +0800 [thread overview]
Message-ID: <20200624102011.4861-1-cgxu519@mykernel.net> (raw)
In metacopy case, we should use ovl_inode_realdata() instead of
ovl_inode_real() to get real inode which has data, so that
we can get correct information of extentes in ->fiemap operation.
