[PATCH] rtlwifi: get buffer_desc before trying to alloc new skb

2015-03-12 Thread Yang Bai
if rtlpriv->use_new_trx_flow == true and we run out of memory to alloc a new skb, we will directly jump to no_new tag with buffer_desc == NULL. Then we will dereference this NULL pointer in function _rtl_pci_init_one_rxdesc. Signed-off-by: Yang Bai --- drivers/net/wireless/rtlwifi/pci.c |

Q: What will happen if I insmod a new version driver when it has already been statically in kernel?

How to map ata_link to physical link and ata_port to physical port

Hi hackers, In our internal usage, we want to map the disk in system like sd{a,b,c} to physical disk slot. When the disk is attached to LSI HBA card, we find that we can rely on the phy attribute of the disk to find the slot since this attribute does not change no matter which kind of disks we att
