# commit 5076190daded2197f62fe92cf69674488be44175

#     mm: slub: be more careful about the double cmpxchg of freelist
#     
#     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.
