Are there some potential problems that I should be aware of if I allocate the memory which doesn't have any relation to peripheral hardwares(i.e. DMA,PCI,serial port and etc) by vmalloc() instead of kmalloc()?

Hi, list

Besides kmalloc() is more efficient, are there some potential problems
that I should be aware of if I allocate the memory which doesn't have
any relation to peripheral hardwares(i.e. DMA,PCI,serial port and etc)
by vmalloc() instead of kmalloc() to avoid the page allocation failure
caused by kmalloc() while there are too many memory fragments?

Thank you for your attention to this matter.
Best Regards.
