Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
netfs: Fix potential for tearing in ->remote_i_size and ->zero_point<br />
<br />
Fix potential tearing in using ->remote_i_size and ->zero_point by copying<br />
i_size_read() and i_size_write() and using the same seqcount as for i_size.<br />
<br />
We need to make sure that netfslib and the filesystems that use it always<br />
hold i_lock whilst updating any of the sizes to prevent i_size_seqcount<br />
from getting corrupted.
