[PATCH v2 0/2] Fix test_resume failure by openning swap device non-exclusively

[Chen Yu]

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 for patch 2 and it turns snapshot_test into a global variable.
Patch 2 opens swap device non-exclusively for test_resume mode, and exclusively for manual
hibernation resume.

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
