2010-06-24md: fix handling of array level takeover that re-arranges devices.NeilBrown6-35/+41
Most array level changes leave the list of devices largely unchanged, possibly causing one at the end to become redundant. However conversions between RAID0 and RAID10 need to renumber all devices (except 0). This renumbering is currently being done in the ->run method when the new personality takes over. However this is too late as the common code in md.c might already have invalidated some of the devices if they had a ->raid_disk number that appeared to high. Moving it into the ->takeover method is too early as the array is still active at that time and wrong ->raid_disk numbers could cause confusion. So add a ->new_raid_disk field to mdk_rdev_s and use it to communicate the new raid_disk number. Now the common code knows exactly which devices need to be renumbered, and which can be invalidated, and can do it all at a convenient time when the array is suspend. It can also update some symlinks in sysfs which previously were not be updated correctly. Reported-by: Maciej Trela <[email protected]> Signed-off-by: NeilBrown <[email protected]>

2010-06-24Restore partition detection of newly created md arrays.NeilBrown1-0/+1
Commit b821eaa572fd737faaf6928ba046e571526c36c6 broke partition detection for md arrays. The logic was almost right. However if revalidate_disk is called when the device is not yet open, bdev->bd_disk won't be set, so the flush_disk() Call will not set bd_invalidated. So when md_open is called we still need to ensure that ->bd_invalidated gets set. This is easily done with a call to check_disk_size_change in the place where the offending commit removed check_disk_change. At the important times, the size will have changed from 0 to non-zero, so check_disk_size_change will set bd_invalidated.

2010-06-09gianfar: Revive the driver for eTSEC devices (disable timestamping)Anton Vorontsov1-2/+1
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.
