'rtl8192_irq_rx_tasklet()' is a tasklet initialized in 'rtl8192_init_priv_task()'. >From this function it is possible to allocate some memory with the GFP_KERNEL flag, which is not allowed in the atomic context of a tasklet. Use GFP_ATOMIC instead. The call chain is: rtl8192_irq_rx_tasklet (in r8192U_core.c) --> rtl8192_rx_nomal (in r8192U_core.c) --> ieee80211_rx (in ieee80211/ieee80211_rx.c) --> RxReorderIndicatePacket (in ieee80211/ieee80211_rx.c) Fixes: 79a5ccd97209 ("staging: rtl8192u: fix large frame size compiler warning") Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c b/drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c index 195d963c4fbb..b6fee7230ce0 100644 --- a/drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c +++ b/drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c @@ -597,7 +597,7 @@ static void RxReorderIndicatePacket(struct ieee80211_device *ieee, prxbIndicateArray = kmalloc_array(REORDER_WIN_SIZE, sizeof(struct ieee80211_rxb *), - GFP_KERNEL); + GFP_ATOMIC); if (!prxbIndicateArray) return; -- 2.25.1 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
