fs: assign sb->s_bdi to default_backing_dev_info if the bdi is going away

2011-03-27T19:00:31+00:00

commit 95f28604a65b1c40b6c6cd95e58439cd7ded3add upstream.

We don't have proper reference counting for this yet, so we run into
cases where the device is pulled and we OOPS on flushing the fs data.
This happens even though the dirty inodes have already been
migrated to the default_backing_dev_info.

Revert "writeback: fix WB_SYNC_NONE writeback from umount"

2010-06-01T09:08:43+00:00

This reverts commit e913fc825dc685a444cb4c1d0f9d32f372f59861.

We are investigating a hang associated with the WB_SYNC_NONE changes,
so revert them for now.

sanitize vfs_fsync calling conventions

2010-05-21T22:31:21+00:00

Now that the last user passing a NULL file pointer is gone we can remove
the redundant dentry argument and associated hacks inside vfs_fsynmc_range.

The next step will be removig the dentry argument from ->fsync, but given
the luck with the last round of method prototype changes I'd rather
defer this until after the main merge window.

At the same time we can kill s_need_restart and local mutex in there.

Leave superblocks on s_list until the end

2010-05-21T22:31:14+00:00

We used to remove from s_list and s_instances at the same
time.  So let's *not* do the former and skip superblocks
that have empty s_instances in the loops over s_list.

The next step, of course, will be to get rid of rescan logics
in those loops.
