# Merge: f639bef 961b33c
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'usercopy-fix-v4.18-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
#     
#     Pull usercopy whitelisting fix from Kees Cook:
#      "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"
