test_resume does not work in current kernel when using swapfile for hibernation. This is because the swap device should be openned non-exclusively in test_resume mode.
Patch 1 is a preparation to turn snapshot_test into a global variable. Patch 2 is the fix to open swap device non-exclusively only for test_resume mode.
Change since v2: Adjust the initialization of fmode and refine the commit message per Rafael's suggestion.
Change since v1: Turn snapshot_test into global variable and do not introduce parameters for swsusp_check() nor load_image_and_restore().
Chen Yu (2): PM: hibernate: Turn snapshot_test into global variable PM: hibernate: Do not get block device exclusively in test_resume mode
