# Merge: 39192106d4ef 59300b36f85f
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Wed Mar 31 10:14:55 2021 -0700
# 
#     Merge tag 'trace-v5.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull ftrace fix from Steven Rostedt:
#      "Add check of order < 0 before calling free_pages()
#     
#       The function addresses that are traced by ftrace are stored in pages,
#       and the size is held in a variable. If there's some error in creating
#       them, the allocate ones will be freed. In this case, it is possible
#       that the order of pages to be freed may end up being negative due to a
#       size of zero passed to get_count_order(), and then that negative
#       number will cause free_pages() to free a very large section.
#     
#       Make sure that does not happen"
