[lvm-devel] LVM2/lib/metadata metadata.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2009-06-10 16:14:40

Modified files:
	lib/metadata   : metadata.c 

Log message:
	In the new _vg_read_for_update(), we always do the check for CLUSTERED vg
	status flag after reading the volume group.  Thus, no need to set the flag
	in vg_read() or clear it later before calling _vg_bad_status_bits().
	
	Also, add back in the !lockingfailed() as part of the CLUSTERED flag check.
	It's unclear why it was removed when the check was moved from
	_vg_bad_status_bits() to inside _vg_lock_and_read().
	There was an open question about the last check in the 'if' stmt for
	lockingfailed() with a previous patch submitted.  However, I would
	defer that right now as it is a separate item and this patch should
	be no functional change by including the !lockingfailed().
	
	Petr acked this patch on 5/26 I just forgot to check it in.
