Subject: [PATCH 8/8] ath11k: Use GFP_ATOMIC instead of GFP_KERNEL in idr_alloc
Date: Tue, 29 Sep 2020 20:15:36 +0300 [thread overview]
Message-ID: <1601399736-3210-9-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1601399736-3210-1-git-send-email-kvalo@codeaurora.org>
From: Govind Singh <govinds@codeaurora.org>
With SLUB DEBUG CONFIG below crash is seen as kmem_cache_alloc
is being called in non-atomic context.
To fix this issue, use GFP_ATOMIC instead of GFP_KERNEL in idr_alloc.
BUG: sleeping function called from invalid context at mm/slab.h:393
