2008-07-23ide: filter out "default" transfer mode values in set_xfer_rate()Bartlomiej Zolnierkiewicz
* Filter out "default" transfer mode values (0x00 - default PIO mode, 0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted /proc/ide/hd?/settings:current_speed setting. Allowing "default" transfer mode values is a dangerous thing to do as we don't support programming controller to the "default" transfer mode and devices often use different values for the default and maximum PIO mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay programmed for higher PIO mode while device will use the lower PIO mode. There is no functionality loss as by using special IOCTLs device can still be programmed to "default" transfer modes (it is only useful for debugging/testing purposes anyway). * Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was previously used by few host drivers to program the controller to PIO0 timings for "default" transfer mode == 0x01 (although some host drivers would program invalid PIO timings instead). * Cleanup ide_set_xfer_rate() and add BUG_ON().

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

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!
