Hi All,

Is it possible that queuecommand be called in ISR time ? (IRQ run level)
I want to do kmalloc with GFP_KERNEL priority in queuecommand (or actually pci_pool_alloc which eventually will call kmalloc in pool getting low in memory).

Thank you,
Rabeeh

You cannot use GFP_KERNEL in this situation - it may block, it may cause further I/O.
