Hello,
On top of
[PATCH 0/7] uprobes: deuglify xol_get_insn_slot/xol_free_insn_slot paths
https://lore.kernel.org/all/20240929144201.ga9...@redhat.com/
To me this change looks like a simplification, but perhaps it can
also be considered as optimization.
Yes, in the contended case xol_get_slot_nr() will be called twice,
the second time after prepare_to_wait_event(), but I don't think it
can hurt in the slow path when the caller is likely going to sleep.
Oleg.
