- Update for latest mdadm-4.1+ patches, this is required by
  jsc#SLE-10078 and jsc#SLE-9348. Mostly the purpose is for
  latest Intel IMSM raid support.
  The following patches also include previous patches with
  new re-ordered prefix numbers.
- Makefile: install mdadm_env.sh to /usr/lib/mdadm (bsc#1111960)
  0000-Makefile-install-mdadm_env.sh-to-usr-lib-mdadm.patch
- Assemble: keep MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flag
  (jsc#SLE-10078, jsc#SLE-9348)
  0001-Assemble-keep-MD_DISK_FAILFAST-and-MD_DISK_WRITEMOST.patch
- Document PART-POLICY lines (jsc#SLE-10078, jsc#SLE-9348)

- policy: support devices with multiple paths.
  (jsc#SLE-10078, jsc#SLE-9348)
  0003-policy-support-devices-with-multiple-paths.patch
- mdcheck: add systemd unit files to run mdcheck. (bsc#1115407)

Subject: [PATCH] Create: Block rounding size to max
Git-commit: 22dc741f63e6403d59c2c14f56fd4791265f9bbb
Patch-mainline: mdadm-4.1+
References: jsc#SLE-10078, jsc#SLE-9348
When passed size is smaller than chunk, mdadm rounds it to 0 but 0 there
means max available space.
Block it for every metadata. Remove the same check from imsm routine.
