[dm-devel] [PATCH 1/3] libmultipath: fix DI_NOIO pathinfo PATH_PENDING handling

[Benjamin Marzinski]

pp->state should only be set to PATH_PENDING if it is currently in
the PATH_UNCHECKED or PATH_WILD states. Otherwise, it should retain
its current state.  Fix this in pathinfo() calls with DI_NOIO, to
match with the rest of the code.
