Kyle Evans a2f08d0ddc pseudofs: return errors from pfs_create_() In D52038, we kind of guess at the reason that pfs_create_dir() failed, which isn't great: it could be EEXISTS, or it could even be ENOMEM. Change the pfs_create_() interfaces to return an error and use a double pointer to return the new node as requested. Outside of the changes in sys/fs/pseudofs, this diff is the result of running the added coccinelle script against in-tree pseudofs and fixing all of the style(9) violations that spatch added. We set *opn to NULL in the failure cases to avoid breaking callers that did actually error-check their results, since the cocci patch does not attempt to handle that in any way.

Kyle Evans a2f08d0ddc pseudofs: return errors from pfs_create_*()

In D52038, we kind of guess at the reason that pfs_create_dir() failed,
which isn't great: it could be EEXISTS, or it could even be ENOMEM.

Change the pfs_create_*() interfaces to return an error and use a double
pointer to return the new node as requested.  Outside of the changes
in sys/fs/pseudofs, this diff is the result of running the added
coccinelle script against in-tree pseudofs and fixing all of the
style(9) violations that spatch added.

We set *opn to NULL in the failure cases to avoid breaking callers that
did actually error-check their results, since the cocci patch does not
attempt to handle that in any way.
