| * UBI: cleanup usage of try_module_getFernando Luis Vázquez Cao2007-07-18
| | | | | | | | | | | | | | | | | | | | | | | | The use of try_module_get(THIS_MODULE) in ubi_get_device_info does not offer real protection against unexpected driver unloads, since we could be preempted before try_modules_get gets executed. It is the caller who should manipulate the refcounts. Besides, ubi_get_device_info is an exported symbol which guarantees protection when accessed through symbol_get.

| * UBI: fix overflow bugVinit Agnihotri2007-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was experiencing overflows in multiplications for volume->used_bytes in vmt.c & vtbl.c, while creating & resizing large volumes. vol->used_bytes is long long however its 2 operands vol->used_ebs & vol->usable_leb_size are int. So their multiplication for larger values causes integer overflows. Typecasting them solves the problem. My machine & flash details: 64Bit dual-core AMD opteron, 1 GB RAM, linux 2.6.18.3. mtd size = 6GB, volume size= 5GB, peb_size = 4MB. heres patch which does the fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | Hi,I came across problem of having two leb with same sequence no.This happens when we continuously write one block again and again and reboot machine before background thread erases those blocks. The problem here was,when we find two blocks with same sequence no,we take the higher one,but we were not updating max seq no,so next block may have the same seqnum. This patch solves this problem.
