2005-07-16[MTD] NAND: Fix broken bad block scan for 16 bit devicesThomas Gleixner
The previous change to read a single byte from oob breaks the bad block scan on 16 bit devices, when the byte is on an odd address. Read the complete oob for now. Remove the unused arguments from check_short_pattern() Move the wait for ready function so it is only executed when consecutive reads happen. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-06-29[MTD] NAND: Reorganize chip lockingThomas Gleixner
The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
