2009-12-10lp: move compat_ioctl handling into lp.cArnd Bergmann
Handling for LPSETTIMEOUT can easily be done in lp_ioctl, which is the only user. As a positive side-effect, push the BKL into the ioctl methods. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-10-16device create: char: convert device_create_drvdata to device_createGreg Kroah-Hartman
Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-07-21device create: char: convert device_create to device_create_drvdataGreg Kroah-Hartman
device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2007-05-08layered parport code uses parport->devDavid Brownell
Update some of the layered parport_driver code to use parport->dev: - i2c-parport (parent of i2c_adapter) - spi_butterfly (parent of spi_master, allowing cruft removal) - lp (creating class_device) - ppdev (parent of parportN device) - tipar (creating class_device) There are still drivers that should be updated, like some of the input drivers; but they won't be any worse off than they are today.

2006-12-13[PATCH] getting rid of all casts of k[cmz]alloc() callsRobert P. J. Day
Run this: #!/bin/sh for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

2006-07-03[PATCH] make more file_operation structs staticArjan van de Ven
Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

2005-04-16Linux-2.6.12-rc2v2.6.12-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!
