"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngfs2: fix quota init duplicate scan\n\ngfs2_quota_init() checks for duplicate quota_change IDs while holding\nqd_lock and the quota hash bucket bitlock. That path used\ngfs2_qd_search_bucket(), which takes a lockref reference via\nlockref_get_not_dead().\n\nOn PREEMPT_RT this may sleep, which is not allowed under the bucket\nbitlock, triggering \"sleeping function called from invalid context\".\n\nUse a no-ref bucket lookup in this path, then continue duplicate\nhandling without taking a lockref there.\n\nRefactor gfs2_qd_search_bucket() to build on top of the no-ref helper\nso lookup traversal stays in one place.\n\nThis patch fixes a bug reported by syzbot."
