Subject: [PATCH v2 0/2] mm/swapfile: release swap info when swap device is unpluged

This series patch try to fix the problem that the resources
corresponding to swap are not effectively released when
the swap partition disk is hot-pluged.

1/2: Extract operations of resource release in the swapoff process.
2/2: release swap info when swap device is unpluged

This is a second version, which addressed some comments:
1. turn first patch into a two patch series. The first does the
code movement with no functional changes and the second does
the actual fix.
