[lustre-devel] [PATCH 141/622] lustre: uapi: add new changerec_type

[James Simmons]

From: Qian Yingjin <qian at ddn.com>

The Lazy Size on MDT is causing the trusted.som xattr to be logged
in the changelog whenever a file is needed to update this xattr
data casued by file open/close or truncate operations.

The original patch landed to the OpenSFS branch fixes this problem
to avoid logging this xattr for every file. This introduces a new
changelog_rec_type that the mdc changelog code needs to be aware
of.
