2008-01-24Kobject: rename kobject_init_ng() to kobject_init()Greg Kroah-Hartman1-2/+2
Now that the old kobject_init() function is gone, rename kobject_init_ng() to kobject_init() to clean up the namespace. Cc: Kay Sievers <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2007-07-19unregister_chrdev() return voidAkinobu Mita1-2/+1
unregister_chrdev() does not return meaningful value. This patch makes it return void like most unregister_* functions. Signed-off-by: Akinobu Mita <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2007-04-04[PATCH] remove protection of LANANA-reserved majorsAndrew Morton1-2/+0
Revert all this. It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups. Which is a bit broken of Amanda (or tar), but this feature isn't important enough to justify the churn.

2007-02-20[PATCH] rework reserved major handlingAndrew Morton1-6/+2
Several people have reported failures in dynamic major device number handling due to the recent changes in there to avoid handing out the local/experimental majors. Rolf reports that this is due to a gcc-4.1.0 bug. The patch refactors that code a lot in an attempt to provoke the compiler into behaving.

2007-02-12[PATCH] register_chrdev_region() don't hand out the LOCAL/EXPERIMENTAL majorsAndrew Morton1-0/+7
As pointed out in http://bugzilla.kernel.org/show_bug.cgi?id=7922, dynamic chardev major allocation can hand out majors which LANANA has defined as being for local/experimental use.

2006-09-30[PATCH] BLOCK: Move extern declarations out of fs/*.c into header files [try #6]David Howells1-0/+1
Create a new header file, fs/internal.h, for common definitions local to the sources in the fs/ directory. Move extern definitions that should be in header files from fs/*.c to fs/internal.h or other main header files where they span directories.

2006-09-29[PATCH] Chardev checking of overlapping rangesAmos Waterland1-5/+23
The code in __register_chrdev_region checks that if the driver wishing to register has the same major as an existing driver the new minor range is strictly less than the existing minor range. However, it does not also check that the new minor range is strictly greater than the existing minor range. That is, if driver X has registered with major=x and minor=0-3, __register_chrdev_region will allow driver Y to register with major=x and minor=1-4.

2006-09-27[PATCH] NOMMU: Set BDI capabilities for /dev/mem and /dev/kmemDavid Howells1-0/+20
Set the backing device info capabilities for /dev/mem and /dev/kmem to permit direct sharing under no-MMU conditions and full mapping capabilities under MMU conditions. Make the BDI used by these available to all directly mappable character devices. Also comment the capabilities for /dev/zero.

2006-03-31[PATCH] Simplify proc/devices and fix early termination regressionJoe Korty1-76/+11
Make baby-simple the code for /proc/devices. Based on the proven design for /proc/interrupts. This also fixes the early-termination regression 2.6.16 introduced, as demonstrated by: # dd if=/proc/devices bs=1 Character devices: 1 mem 27+0 records in 27+0 records out This should also work (but is untested) when /proc/devices >4096 bytes, which I believe is what the original 2.6.16 rewrite fixed.

2006-03-28[PATCH] Make most file operations structs in fs/ constArjan van de Ven1-1/+1
This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: Arjan van de Ven <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2005-07-12[PATCH] cdev: cdev_put oopsBrian King1-1/+2
While fixing an oops in the st driver in a dirty release path, I encountered an oops in cdev_put for cdevs allocated using cdev_alloc. If cdev_del is called when the cdev kobject still has an open user, when the last cdev_put is called, the cdev_put will call kobject_put, which will end up ultimately releasing the cdev in cdev_dynamic_release. Patch fixes the oops by preventing cdev_put from accessing freed memory.

2005-04-17[PATCH] revert fs/char_dev.c CONFIG_BASE_FULL changeDavid Brownell1-2/+1
This reverts a fs/char_dev.c patch that was merged into BK on March 3. The problem is that it breaks things ... __register_chrdev_region() has a block of code, commented "temporary" for over two years now, which fails rudely during PCMCIA initialization or other register_chrdev() calls, because it doesn't "degrade to linked list". This keeps whole subsystems from working. A real fix to that "temporary" code should be possible, using some better scheme to allocate major numbers, but it's not something I want to spend time on just now.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+449
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!
