Fixed voltage is a kind of linear mapping where n_voltages is 1. This change allows [list|map]_voltage_linear to be used for fixed voltage. For fixed voltage, n_voltages is 1 and the only valid selector is 0. Thus we actually don't care the uV_step setting.

The voltage mapping table for LDO2 is exactly the same as VDCDCx. Thus we can use one mapping table for both LDO2 and VDCDCx instead of duplicating the mapping table. Signed-off-by: NAxel Lin <axel.lin@gmail.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

The min_uV and max_uV are not used in this driver. For table based voltage mappings, we can get min_uV and max_uV by info->table[0] and info->table[table_len -1]. Thus remove min_uV and max_uV from struct tps_info. Signed-off-by: NAxel Lin <axel.lin@gmail.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.

If I/O needs retrying and only bypassed priority groups are available, set the pg_init_delay_retry flag to wait before retrying. If, for example, the reason for the bypass is that the controller is getting reset or there is a firmware upgrade happening, retrying right away would cause a flood of log messages and retries for what could be a few seconds or even several minutes.
