* UBI: cleanup usage of try_module_getFernando Luis Vázquez Cao2007-07-181-5/+0
| | | | | | | | | | | | 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 Agnihotri2007-07-182-6/+11
| | | | | | | | | | | | | | | | | | | | 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.

* UBI: bugfix in sqnum calculationBrijesh Singh2007-07-181-3/+3
| | | | | | | | | | | | | 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.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-172-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

That means that my parser tries to parse all the code, including code in the #else branch or code that is not often compiled because the driver is not very used (or not used at all).
