[PATCH 0/6] Enhancements and bug fixes for --mount

[Cong Wang]

From: Cong Wang <xiyou.wangcong-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

This patchset is based on "usrmove" branch, contains several bug fixes
and some enhancements for the new option '--mount'.

With these patches applied, kdump works well with dracut (the lvm case).

All patches are available at:

	git://github.com/congwang/dracut.git #kdump

Cong Wang (6):
  Add mount points even not in hostonly mode
  Check module dependencies of mount points
  Fix get_maj_min() to follow symlink
  Pass device name instead of major:minor in for_each_host_dev_fs()
  nfs: fix regex patterns in check()
  lvm: pass the correct rd.lvm.lv parameter

[PATCH 1/6] Allow to add mount points even not in hostonly mode

[Cong Wang]

From: Cong Wang <xiyou.wangcong-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Don't force --mount only working in hostonly mode, let users decide.
With this patch, people can still combine -H --mount '...' if they
want to use it in hostonly mode.

[PATCH 2/6] Check module dependencies of mount points

[Cong Wang]

From: Cong Wang <xiyou.wangcong-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

[PATCH 3/6] Fix get_maj_min() to follow symlink

[Cong Wang]

From: Cong Wang <xiyou.wangcong-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Otherwise get_maj_min /dev/mapper/vg_cr0-lv_home will return 0:0.
