Hi
I'm looking at some performance graphs and udev rule 99-nfs.rules seems to be
taking some unnecessary CPU time when the system is creating and removing a
lot of devices in the system. It looks like 'nfsrahead' is always
'parsing' something in mnt_table_parse_line - while technically all
the entries in nfs.conf are simply commented out, so there is nothing
'nfsrahead' should be doing and it should just quickly exit.
Also is it really worth this done through udev system ? - when possibly thing
could be solved via udev monitoring in case something really is needed to
change these setting for BDI (although this change is substantially harder to
develop).
Regards
Zdenek
