Subject: ocfs2: Update VFS inode's id info after reflink.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c21a534e2f24968cf74976a4e721ac194db30ded;p=openwrt%2Fstaging%2Fblogic.git

ocfs2: Update VFS inode's id info after reflink.

In reflink we update the id info on the disk but forgot to update
the corresponding information in the VFS inode.  Update them
accordingly when we want to preserve the attributes.
