Subject: [GIT PULL] Btrfs fix for 5.2-rc5

Hi,

here's one regression fix to TRIM ioctl. The range cannot be used as
its meaning can be confusing regarding physical and logical addresses.
This confusion in code led to potential corruptions when the range
overlapped data.

The original patch made it to several stable kernels and was promptly
reverted, the version for master branch is different due to additional
changes but the change is effectively the same.

Please pull, thanks.
