[lustre-devel] [REQUEST] Reserve OBD_CONNECT2_PERFSTATS flag value 0x100000000000ULL

[Andreas Dilger]

Hi George,
I've seen your patch and confirm that this does not conflict with any in-use
flags.  It isn't totally clear that a compat flag is necessary in this case,
but it is OK to reserve the flag and then it can be un-reserved if it turns
out not to be needed.

Cheers, Andreas
