Subject: Problem in src_cmpxattr?
Date: Thu, 13 Nov 2014 15:03:35 +0100	[thread overview]
Message-ID: <5464BA37.1080801@cern.ch> (raw)

Hi there,

I need to create an object O (if it doesn't exist) and set an xattr on 
it based on a condition that another xattr in a different object (X) 
should obey. For this, on the same write operation (called on O) I call 
create (not exclusively), setxattr and src_cmpxattr (with X as the 
src_oid), respectively.

What I noticed is that if object O does not exist, the src_cmpxattr 
returns -ENOENT (even if object X does exist). IMO, this error should 
only be returned if X didn't exist and not O.

Is this the correct expectation for what src_cmpxattr should do (compare 
an xattr on the given source object to the parameters given)?
Is this somehow expected? If so, is there any other way that I can 
accomplish what I need as mentioned above?


Thank you in advance,
