Revision 4bb6e96ab808f88d746343637f0cc2243b527da5 authored by Sebastian Andrzej Siewior on 28 June 2018, 06:26:01 UTC, committed by Linus Torvalds on 28 June 2018, 18:16:44 UTC
In commit 804209d8a009 ("lib/percpu_ida.c: use _irqsave() instead of local_irq_save() + spin_lock") I inlined alloc_local_tag() and mixed up the >= check from percpu_ida_alloc() with the one in alloc_local_tag(). Don't alloc from per-CPU freelist if ->nr_free is zero.
