Subject: [PATCH] mpathpersist: remove broken/unused code
|
|
|
|
The test for an empty pp->dev in updatepaths() dates back to when
|
|
disassemble_map() didn't fill in pp->dev for newly added paths, and it
|
|
was meant to catch paths that got added by disassemble_map(). With the
|
|
mpathpersist speedup code, all paths get added by disassemble_map().
|
|
However, disassemble_map() now calls devt2devname() to set pp->dev if
|
|
possible. This means that there is no point in calling devt2devname()
|
|
again in updatepaths(). If for some reason it did return success, the
|
|
current code would still fail, since it doesn't set pp->udev in this
|
|
code path. The best thing to do if disassemble_map() couldn't set
|
|
pp->dev is simply to fail the path.
