Subject: [lustre-devel] [PATCH 06/25] lustre: lmv: getattr_name("..") under striped directory
Date: Mon,  2 Aug 2021 15:50:26 -0400	[thread overview]
Message-ID: <1627933851-7603-7-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1627933851-7603-1-git-send-email-jsimmons@infradead.org>

From: Lai Siyao <lai.siyao@whamcloud.com>

For getattr_name(".."), it should return FID of the master object for
striped directories. This includes changes on both client and server:
* lmv_getattr_name() should use master object FID if it's looking up
  "..".
* mdt_raw_lookup() should check parent object is sub stripe, if so
  it needs to lookup again to get master object FID. For old client
  without above change this needs to be checked twice.

This is needed by NFS export, because ll_get_parent() find parent by
getattr_name("..").

Reenable check_fhandle_syscall and update sanityn test_102.

WC-bug-id: https://jira.whamcloud.com/browse/LU-14826
