[PULL] [PATCH 0/6] Support for 'pending changes'

[David Sterba <dsterba@suse.cz>]

There are some actions that modify global filesystem state but cannot be
performed at the time of request, but rather later at the transaction commit
time when the filesystem is in a known state.

The change can be requested from any context and is permanent after sync. This
changes the semantics for the sysfs files that modify label or feature bits,
but I think this does not break existing applications.

You can pull the series from
