This fixes issues with importing ZFS pools, such as when the ZFS device is a partition that covers the end of the disk. See: https://github.com/zfsonlinux/zfs/issues/1684

Fix libblkid support
|
|
|
|
libblkid support is dormant because the autotools check is broken and
|
|
liblkid identifies ZFS vdevs as "zfs_member", not "zfs". We fix that
|
|
with a few changes:
|
|
|
|
First, we fix the libblkid autotools check to do a few things:
|
|
|
|
1. Make a 64MB file, which is the minimum size ZFS permits.
|
|
2. Make 4 fake uberblock entries to make libblkid's check succeed.
|
|
3. Return 0 upon success to make autotools use the success case.
|
|
4. Include stdlib.h to avoid implicit declration of free().
|
|
5. Check for "zfs_member", not "zfs"
|
|
6. Make --with-blkid disable autotools check (avoids Gentoo sandbox violation)
|
|
7. Pass '-lblkid' correctly using LIBS not LDFLAGS.
|
|
|
|
Second, we change the libblkid support to scan for "zfs_member", not
|
|
"zfs".
|
|
|
|
This makes --with-blkid work on Gentoo.
