Dear Lustre-devel,
It appears that stating a non-existent file on Lustre causes a negative
dentry to be created, while opening it does not. If I understand
correctly, this also means that every open of a non-existent file that
misses the dentry cache causes an RPC to the MDS. Is there a reason for
the difference?
Thanks,
John
