lvm2/fsadm-add-support-for-btrfs.patch
LiuhuaMelody Wang 8ac4ae703b Accepting request 393600 from home:scarabeus_iv:branches:Base:System
- Update patch use-mirrortype-asdefault-whenclvmdrunning.patch
  to match up the patches/pvmove_support_clustered_vg.diff and not
  use the define declared only when building clvm codebase;
  it is still broken if someone changes the PID location, but at least
  it now does not depend on clvm code
- Regenerate_initrd in post of the lvm2 main pkg
- Update baselibs to point to split-out devicemapper libraries

- Keep in sync the common configuration options that are shared among
  all the variants dm/lvm2/clvm

- Provide symlinks to 1.02 versions of dm and dm-event libs
  * this should sort out binary packages without the need of double
    rebuilding

- Update to 2.02.152 release, read WHATS_NEW for detailed log.
- Refresh patches:
  * 10-dm.rules-Reset-state-variable-for-spurious-events.patch
  * device-mapper-gcc-warnings.patch
  * device-mapper-link.patch
  * udev-Check-for-DM_NR_VALID_PATHS.patch
- Slightly tweak btrfs patch as the code changed for the detection:
  * fsadm-add-support-for-btrfs.patch

- Build and install properly cluster files
- Remove csm-converter.tar.gz as the evms was last present on sle10
  and thus migration is bit out of scope today

- Add pre_checkin.sh to allow syncing of patches between packages:
  workflow = add everything to lvm2.spec and run pre_checkin.sh

Subject: [Patch v2] fsadm: add support for btrfs
Check: mount the device first and then run`btrfs filesystem scrub start
-B` command
Reisze: find the mount point first and resize the filesystem after get
the device id since there are maybe several devices underneath btrfs
filesystem

Hi David,
This is the patch I sent to upstream. It works fine based on our test.
Please shed your light and thank you for taking time to review.
Regards,
Lidong
