Subject: [RFC v2 51/83] Rebuild: directory inode.
Date: Sat, 10 Mar 2018 10:18:32 -0800
Message-ID: <1520705944-6723-52-git-send-email-jix024@eng.ucsd.edu> (raw)
In-Reply-To: <1520705944-6723-1-git-send-email-jix024@eng.ucsd.edu>

From: Andiry Xu <jix024@cs.ucsd.edu>

When vfs issues a read inode command, or when the inode is newly allocated,
walk through the inode log to rebuild inode information and the radix tree.
