To my knowledge, the problem of "failed to inform kernel of partition changes" continues with parted-2.2.

Based on reports from users of GParted, the problem first appeared after parted-1.8.8 with some development snapshots from git (e.g., parted-1.8.8 + development code in git) and parted-1.9.0.

Several attempts have been made to address this problem, but none appear to have been able to eradicate this bug. I believe that most recent attempt to resolve this problem is the following parted git commit:
  libparted: avoid race in informing the kernel of partition table changes

This above commit is included in the parted-2.3 release.

Would you be able to test again using parted-2.3?

Unfortunately the problem does not reliably occur on all computer systems, which has made this bug very elusive.

Reports from users of GParted regarding file system resize problems that occurred when this problem happened can be seen in the in the following GParted forum post:
  WARNING! Problem Resizing File Systems with GParted
