[PATCH] scsi: cxlflash: Change return type for fault handler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t")
