Subject: [PATCH 0/2] nilfs2: asynchronous super block updates
Date: Sun,  6 Jun 2010 07:19:07 +0900	[thread overview]
Message-ID: <1275776349-22820-1-git-send-email-jir@unicus.jp> (raw)

Hi,

These are patches to update super blocks in turns.

First patch separates super block validity check from nilfs_commit_super,
and moved the function into callers.

Second patch separates super block pointer updates from nilfs_commit_super.

Callers which intend to update super root pointer in super block must call
before calling nilfs_commit_super.  Now nilfs_commit_super replicates
the super block information except super root pointer information when
passed dupsb as non-0.  When dupsb is 0, nilfs_commit_super just clears
the dirty flag and calls nilfs_sync_super.
