Subject: [RFC v2 21/83] Add log structure.
Date: Sat, 10 Mar 2018 10:18:02 -0800	[thread overview]
Message-ID: <1520705944-6723-22-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>

NOVA log is a singly linked list of 4KB pmem pages.
Each log page consists of two parts: 4064 bytes for log entries,
and 32 bytes for page tail structure. Page tail contains metadata
about the log page and the address of the next log page in the
linked list.
