| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing register reads, it is possible for there to be a stale data ready bit set which will cause subsequent reads to return prematurely with incorrect data.

When NOR erases, it first fills PEBs with zeroes, then sets all bytes to 0xFF. Filling with zeroes starts from the end of the PEB. And when power is cut, this results in PEBs containing correct EC and VID headers but corrupted with zeros at the end. This confuses UBI and it mistakinly accepts these PEBs and associate them with LEBs. Fis this issue by zeroing EC and VID magics before erasing PEBs, to make UBI later refuse zem.

In this case the paranoid check fails. I is just wrong to assume that PEBs which do not have EC headers always contain all 0xFF. Such assumption should not be made on the I/O level, which is quite low. Thus, just kill the check. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

This is OK if the corrupted empty space is somewhere near that offset. But if the corruption is far at the end of the LEB, we will dump all 0xFF bytes and complitely ignore the interesting data. This is observed on a PPC ("kilauea") with NOR flash. This patch changes the behavior and teaches UBIFS to print only interesting data. I.e., now we find where corruption starts and start dumping from that offset. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Reviewed-by: Adrian Hunter <Adrian.Hunter@nokia.com>

If write-buffer does not use the timer, indicate it with the wbuf->no_timer variable, instead of using the wbuf->softlimit variable. This is better because wbuf->softlimit is of ktime_t type, and the ktime_to_ns function contains 64-bit multiplication. 2. Do not call the 'hrtimer_cancel()' function for write-buffers which do not use timers. 3. Do not cancel the timer in 'ubifs_put_super()' because the synchronization function does this.

This might lead to false positive lockdep reports. Since lockdep isn't aware of the fact that only a single interrupt source is enabled it warns about possible deadlocks that in reality won't happen, like the one below. To fix this disable lockdep before enabling interrupts.

It does that by mounting a stacking block device on top of an osd object. For example, if you create a 2G object on an OSD device, you can then use this module to present that 2G object as a Linux block device. See inside patch for exact documentation.
