The function path_is_under() doesn't modify the paths pointed by its
arguments but only browse them. Constifying this pointers make a cleaner
interface to be used by (future) code which may only have access to
const struct path pointers (e.g. LSM hooks).

I suspect the version bump is just to signify that the table now specifies
pad macro/links instead of SOR/sublinks.
For our usage of the table, just recognising the new version is enough.

Variable ret is reset in the loop, and its value will be 0 during the
second and after repeat of the loop. If pci_alloc_consistent() returns a
NULL pointer then, it will leaves with return value 0. 0 means no error,
which is contrary to the fact. This patches fixes the bug, explicitly
assigning "-ENOMEM" to return variable ret on the path that the call to
pci_alloc_consistent() fails.

Passing one instead of 8 or 16 arguments reduces the size of the

This patch addresses 4 problems in the module probe/remove:
- When hisi_sas_shost_alloc() fails after we alloc shost memory, we
should free shost memory before the function returns.
- When hisi_sas_probe() fails after we alloc the HBA memories, we
should also free the HBA memories.
- We should free shost memory at the end of hisi_sas_remove().
- sha->core.shost is set twice, so remove extra set.

It is easy to forget adding/removing entries at the

there are lots of missing stuff out there.
Now that we're doing a hard work converting entries to ReST,

some tool that would help to verify that this file is kept
