Add support for devid and phys_path keys in vdev disk labels This is foundational work for ZED. Updates a leaf vdev's persistent device strings on Linux platform * only applies for a dedicated leaf vdev (aka whole disk) * updated during pool create|add|attach|import * used for matching device matching during auto-{online,expand,replace} * stored in a leaf disk config label (i.e. alongside 'path' NVP) * can opt-out using env var ZFS_VDEV_DEVID_OPT_OUT=YES Some examples: path: '/dev/sdb1' devid: 'scsi-350000394a8ca4fbc-part1' phys_path: 'pci-0000:04:00.0-sas-0x50000394a8ca4fbf-lun-0' path: '/dev/mapper/mpatha' devid: 'dm-uuid-mpath-35000c5006304de3f' Signed-off-by: Don Brady <don.brady@intel.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2856 Closes #3978 Closes #4416

Only build devname2devid when libudev headers are available Accidentally introduced by commit 39fc0cb. The devname2devid utility which depends on libudev must only be built when libudev headers are available. This is accomplished through an AM_CONDITIONAL.
