2006-09-27[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o
The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

i2c-dev: Use a list for data storage Use a list instead of a static array for storing the i2c-dev data. Given that most systems have less than 10 i2c busses, most of the space was wasted, so this saves around 1 kB of memory (2 kB on 64-bit archs.) The drawback is that lookup was in O(1) and is now in O(N), but given that the values of N are always small, I don't think this is a problem.

2006-08-26[PATCH] i2c: tps65010 build fixesDavid Brownell
The tps65010.c driver in the main tree never got updated with build fixes since the last batch of I2C driver changes; and the genirq trigger flags were updated wierdly too. This also includes a minor tweak to reduce the frequency used to poll for unplug-the-AC-power on the TPS chips that don't provide relevant IRQs. It _would_ be nice to sense whether there's even a battery, but that'd normally be an HDQ/1-wire interface to a smart battery, and such APIs aren't standardized.

2006-08-06[PATCH] SCX200_ACB: eliminate spurious timeout errorsDavid Woodhouse
While busy-waiting for completion, check the hardware after scheduling; don't schedule and then immediately check the _timeout_. If the yield() took a long time (as it does on my OLPC prototype board when it's busy), we'd report a timeout even though the hardware was now ready. This fixes it, and also switches the yield() for a cond_resched() because we don't actually want to be _that_ nice about it. I see nice tightly-packed SMBus transactions now, rather than waiting for milliseconds between successive phases. Actually, we shouldn't be busy-waiting here at all. We should be using interrupts. That's an exercise for another day though.

Commit 02dd7ae2892e5ceff111d032769c78d3377df970 ("[PATCH] i2c-i801: Merge setup function") has a missing return 0 in the _probe() function. This means the error path is always executed and pci_disable_device() is called even when the device just got successfully enabled. Having the SMBus device disabled makes some systems (eg. Fujitsu-Siemens Lifebook E8010) hang hard during power-off.
