# This is just a cleanup addition to Jann's fix to properly update the # transaction ID for the slub slowpath in commit fd4d9c7d0c71 ("mm: slub: # add missing TID bump.."). # # The transaction ID is what protects us against any concurrent accesses, # but we should really also make sure to make the 'freelist' comparison # itself always use the same freelist value that we then used as the new # next free pointer. # # Jann points out that if we do all of this carefully, we could skip the # transaction ID update for all the paths that only remove entries from # the lists, and only update the TID when adding entries (to avoid the ABA # issue with cmpxchg and list handling re-adding a previously seen value). # # But this patch just does the "make sure to cmpxchg the same value we # used" rather than then try to be clever. # # Acked-by: Jann Horn <jannh@google.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> #
