    We are trying to understand how linux kernel code accesses and
utilizes MSI-X PBA (Pending Bit Array) array.
There is a MSI-X howto document that mentions about PBA array but we
could not locate in kernel where it is accessed and used.

Any help to locate the code that uses the array will be appreciated.
