[Pvfs2-developers] patches: misc small fixes

[Phil Carns]

These are all pretty minor:

mod-parm-desc.patch:
--------------------
The pvfs2 kernel module is missing the parameter description for the 
op_timeout_secs option that can be set at insmod time.

server-gossip-errno.patch:
--------------------------
The pvfs2-server is trying to use errno to propigate errors from 
gossip_enable_file(), but this function returns its error code in the 
return value.  I think maybe the errno handling logic may have just been 
mistakenly pasted from the fopen() error handling earlir in this same file.

mgmt-getconfig-wait.patch:
--------------------------
I don't think this makes a significant difference, but all of the 
mgmt*.sm state machines are using mgmt_wait and mgmt_release to handle 
their operations, except for mgmt-getconfig which is using sys_wait and 
sys_release.  This patch updates mgmt-getconfig to match the other mgmt 
state machines.

pvfs2-rm.patch:
---------------
This is an old patch that apparently just forgot to submit a long time 
ago.  At any rate, it makes two changes to pvfs2-rm.  First of all, it 
updates pvfs2-rm to use the gen_credentials() function to fill in its 
credentials rather than manually setting the credential fields.  It also 
introduces some extra sanity checking on removal of objects that appear 
to be directories.  I think some error handling has been beefed up 
elsewhere since the time this patch was generated, so the sanity check 
isn't as important any more- but it does still result in a better error 
message if you try to remove a normal file as if it is a directory.
