Subject[GIT PULL] usercopy fix for v4.18-rc8
Hi,

Please pull this usercopy fix for v4.18-rc8. Bart Massey discovered that
the usercopy whitelist for JFS was incomplete: the inline inode data may
intentionally "overflow" into the neighboring "extended area", so the
size of the whitelist needed to be raised to include the neighboring
field.

Thanks!
