Subject: hfsplus: make hfsplus_sync_fs() static
This patchset makes HFSPLUS file-system stop using the VFS
'->write_supers()' callback and the '->s_dirt' superblock field because I
plan to remove them once all users are gone.
Like the other similar patchsets, we switch to a delayed job for writing
out the superblock instead of using the 's_dirt' flag. Additionally, this
patch-set includes several clean-ups.
Reminder:
The goal is to get rid of the 'sync_supers()' kernel thread. This kernel
thread wakes up every 5 seconds (by default) and calls '->write_super()'
for all mounted file-systems. And the bad thing is that this is done even
if all the superblocks are clean. Moreover, many file-systems do not even
need this end they do not register the '->write_super()' method at all
(e.g., btrfs).
So 'sync_supers()' most often just generates useless wakeups and wastes
power. I am trying to make all filesystems independent of
'->write_super()' and plan to remove 'sync_supers()' and '->write_super()'
completely once there are no more users.
Tested using the fsstress test from the LTP project.
This patch:
Make hfsplus_sync_fs() static because it is used only in fs/hfsplus/super.c.
