2007-07-18UBI: bugfix in error pathArtem Bityutskiy
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>

2007-07-18UBI: minor comma fixArtem Bityutskiy
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>
2007-07-18UBI: use vmalloc for large buffersArtem Bityutskiy
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>
2007-07-18UBI: add few more commentsArtem Bityutskiy
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>
2007-07-18UBI: set correct gluebi device sizeArtem Bityutskiy
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>
2007-07-18UBI: do not let to read too muchArtem Bityutskiy

2007-07-18UBI: fix error path in create_vtbl()Artem Bityutskiy
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.

2007-07-17Revert drivers/ide/ide.c scsi_cmd_ioctl() usage changesLinus Torvalds
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.

2007-07-17[ISDN] HiSax netjet_s: code movement, prep for hotplugJeff Garzik
1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig. 2) Break up setup_netjet_s() into three separate internal functions. This helps facilitate upcoming use of PCI hotplug API, and in addition makes the code much easier to follow. No code is changed, just moved around. I even kept the out-of-favor "return(0)" style used in the current source code. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-07-17md: change bitmap_unplug and others to void functionsNeilBrown
bitmap_unplug only ever returns 0, so it may as well be void. Two callers try to print a message if it returns non-zero, but that message is already printed by bitmap_file_kick. write_page returns an error which is not consistently checked. It always causes BITMAP_WRITE_ERROR to be set on an error, and that can more conveniently be checked. When the return of write_page is checked, an error causes bitmap_file_kick to be called - so move that call into write_page - and protect against recursive calls into bitmap_file_kick. bitmap_update_sb returns an error that is never checked. So make these 'void' and be consistent about checking the bit.
