In the Linux kernel, the following vulnerability has been resolved:

netfs: Fix potential for tearing in ->remote i size and ->zero point

Fix potential tearing in using ->remote i size and ->zero point by copying i size read() and i size write() and using the same seqcount as for i size.

We need to make sure that netfslib and the filesystems that use it always hold i lock whilst updating any of the sizes to prevent i size seqcount from getting corrupted.
