Subject: os/FileStore: For getxattr, enlarge the value size avoid try again.
X-Git-Tag: v9.0.0~91^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=f07f394d03818cd73209dbc3e5925f515caad562;p=ceph.git

os/FileStore: For getxattr, enlarge the value size avoid try again.

Even the size of content of user.ceph._ is larger than 100. It will try
again. Avoid this, enlarge the buffer size which use
CHAIN_XATTR_MAX_BLOCK_LEN.
