Use udev to create /dev/zvol/[dataset_name] links This commit allows zvols with names longer than 32 characters, which fixes issue on https://github.com/behlendorf/zfs/issues/#issue/102. Changes include: - use /dev/zd* device names for zvol, where * is the device minor (include/sys/fs/zfs.h, module/zfs/zvol.c). - add BLKZNAME ioctl to get dataset name from userland (include/sys/fs/zfs.h, module/zfs/zvol.c, cmd/zvol_id). - add udev rule to create /dev/zvol/[dataset_name] and the legacy /dev/[dataset_name] symlink. For partitions on zvol, it will create /dev/zvol/[dataset_name]-part* (etc/udev/rules.d/60-zvol.rules, cmd/zvol_id).

Fix autoconf variable substitution in udev rules. Change the variable substitution in the udev rule templates according to the method described in the Autoconf manual; Chapter 4.7.2: Installation Directory Variables. The udev rules are improperly generated if the bindir parameter overrides the prefix parameter during configure. For example: # ./configure --prefix=/usr/local --bindir=/opt/zfs/bin The udev helper is installed as /opt/zfs/bin/zpool_id, but the corresponding udev rule has a different path: # /usr/local/etc/udev/rules.d/60-zpool.rules ENV{DEVTYPE}=="disk", IMPORT{program}="/usr/local/bin/zpool_id -d %p" The @bindir@ variable expands to "${exec_prefix}/bin", so it cannot be used instead of @prefix@ directly. This also applies to the zvol_id helper. Closes #283. 2011-06-17 19:02:36 +04:00			`KERNEL=="zd*" SUBSYSTEM=="block" ACTION=="add\|change" PROGRAM="@bindir@/zvol_id $tempnode" SYMLINK+="zvol/%c %c"`
