* UBI: bugfix in error pathArtem Bityutskiy2007-07-18
| | | | | | | | | When volume creation fails, we have to set ubi->volumes[vol_id] back to NULL. This patch also tweaks some debugging stuff. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: use is_power_of_2()Vignesh Babu2007-07-18

* UBI: fix freeing ubi->vtbl while unloadingVinit Agnihotri2007-07-18
| | | | | | | | ubi->vtbl is allocated using vmalloc() in vtbl.c empty_create_lvol(), but it is freed in build.c with kfree() Signed-off-by: Vinit Agnihotri <vinit.agnihotri@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBI: minor comma fixArtem Bityutskiy2007-07-18
| | | | | | | | | | | | | | | | | | Use coma at the the last elements of structure initializer. Daniel Stone's explanation: Because it turns: - .attr = foo + .attr = foo, + .bar = baz into: + .bar = baz, i.e., far less likely to screw up a merge. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: use vmalloc for large buffersArtem Bityutskiy2007-07-18
| | | | | | | UBI allocates temporary buffers of PEB size, which may be 256KiB. Use vmalloc instead of kmalloc for such big temporary buffers. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: add few more commentsArtem Bityutskiy2007-07-18
| | | | | | | Add few comments above ubi_scan_add_used() to explain why it is so complex. Requested by Satyam Sharma <satyam.sharma@gmail.com>. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: set correct gluebi device sizeArtem Bityutskiy2007-07-18
| | | | | | | | In case of static volumes, make emulated MTD device size to be equivalent to data size, rather then volume size. Reported-by: John Smith <john@arrows.demon.co.uk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: do not let to read too muchArtem Bityutskiy2007-07-18
| | | | | | | In case of static volumes it is prohibited to read more data then available. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: fix error path in create_vtbl()Artem Bityutskiy2007-07-18
| | | | | | | | | | | There were several bugs in volume table creation error path. Thanks to Satyam Sharma <satyam.sharma@gmail.com> and Florin Malita <fmalita@gmail.com> for finding and analysing them: http://lkml.org/lkml/2007/5/3/274 This patch makes ubi_scan_add_to_list() static and renames it to add_to_list(), just because it is not needed outside scan.c anymore.

* Revert drivers/ide/ide.c scsi_cmd_ioctl() usage changesLinus Torvalds2007-07-17
| | | | | | | | | | | | | The old IDE driver is not ready to take generic SCSI commands, even if it uses them for some specific issues (ie the tray open/close ioctls for IDE CD-ROM's). Pointed out by Bartlomiej. I'm sure we'll have it fixed properly soon enough, but for now we should not allow it to cause problems.

| * [S390] qdio: output queue stall on FCP and network devicesFrank Pavlic2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | When running QIOASSIST enabled qdio devices in a z/VM environment the output queue for such devices stall in heavy workload situations. When SQBS and EQBS instructions returns CCQ=96 qdio does not reissue the instruction again with the register settings done by millicode but processed the returned qdio buffer. This is wrong. qdio has to reissue the instruction once again on CCQ=96, as we already do it for CCQ=97.
