These patches fix similar issues that have different origin commits.
User-provided mount parameters are intended to have upper limits, but
are validated after their values are converted from seconds to jiffies,
which can lead to an integer overflow.

Murad Masimov (4):
  cifs: Fix integer overflow while processing acregmax mount option
  cifs: Fix integer overflow while processing acdirmax mount option
  cifs: Fix integer overflow while processing actimeo mount option
  cifs: Fix integer overflow while processing closetimeo mount option
