  "message": "pps: make idr lock a mutex and protect idr_pre_get\n\nNow pps_idr_lock is never used in interrupt context so we can replace\nspin_lock_irq/spin_unlock_irq with plain spin_lock/spin_unlock. But\nthere is also a potential race condition when someone can steal an id\nwhich was allocated by idr_pre_get before it is used. So convert spin\nlock to mutex and protect the whole id generation process.\n\nSigned-off-by: Alexander Gordeev \u003clasaine@lvk.cs.msu.su\u003e\nCc: Rodolfo Giometti \u003cgiometti@linux.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
