Hi Ted,

Following changes to v1 as requested by Jan.

Thanks,
Amir.

Changes since v1:
- factor out helpers
- race free test as suggested by Jan

Amir Goldstein (3):
  vfs: add the sb_start_intwrite_trylock() helper
  ext4: factor out helper ext4_sample_last_mounted()
  ext4: do not update s_last_mounted of a frozen fs
