[Linux-cluster] dlm_lock returns EAGAIN

[Daniel Phillips]

Hi Patrick,

An EAGAIN leaks through to dlm_lock via dlm_write, when lock contention 
is local.  Are you sure this is what you want?  It would mean everybody 
has to handle EAGAIN in two places, once right after the call and again 
in the ast.  I'd prefer the dlm_lock call just succeeds and delivers 
EGAIN to the ast, even if the lock is local.

In dlm-kernel/src/locking.c, line 996 (dlm_convert_stage2):

   ret = lkb->lkb_retstatus = -EAGAIN;

Regards,

Daniel
