[lustre-devel] [PATCH 096/151] lustre: fid: improve seq allocation error messages

[James Simmons]

From: Emoly Liu <emoly at whamcloud.com>

When MDTs are waiting for MDT0000 to start the master sequence
server and be granted a meta sequence for the first time, in case
of "-EINPROGRESS", the limited console messages would be clearer
and better than many error messages.

WC-bug-id: https://jira.whamcloud.com/browse/LU-10392
