The top-level Documentation/ directory is unmanageably large, so we should take any obvious opportunities to move stuff into subdirectories. These sched-*.txt files seem an obvious easy case. Signed-off-by:

Fix kernel-doc function prototype parsing which was exposed by vunmap() by allowing more than one '*' before the function name. Error(linux-2.6.24-mm1//mm/vmalloc.c:438): cannot understand prototype: 'struct page **vunmap(const void *addr) ' Signed-off-by:

Factor out file-specific ioctl code into smaller helper functions, away from file_ioctl(). This helps code readability and also reduces indentation inside case statements. Signed-off-by:

Rename old vfs_ioctl to do_ioctl, because the comment above it clearly indicates that it is an internal function not to be exported to modules; therefore it should have a more traditional do_XXX name. The new do_ioctl is exported in fs.h but not to modules. Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should preferably be reserved to callable VFS functions which modules may call, as many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL modules so others can use it (including Unionfs and eCryptfs). Add DocBook for new vfs_ioctl. [akpm@linux-foundation.org: fix build] Signed-off-by:

The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active high) from IRQ settings. There are devices that have IAS=0 but still need the IRQ to trigger on a rising edge. With this patch, machines with DS1WM that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data. Signed-off-by:

The gl_owner_pid field is used to get the lock owning task by its pid, so make it in a proper manner, i.e. by using the struct pid pointer and pid_task() function. The pid_task() becomes exported for the gfs2 module. Signed-off-by:

This commit: commit 8efe4440 Author: Andres Salomon <dilinger@queued.net> Date: Wed Dec 12 14:12:56 2007 -0500 power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs attributes with one more entry than the number of enums in power_supply.h. This leads to some attributes containing the value of the attribute right after it. For example, temp_ambient would have the value of time_to_empty_now. In my case, I had time_to_full_avg have the value which should be in model_name, when the former was usually empty.

This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step. Signed-off-by: -

Request from rusty: Just cleaning up patches for 2.6.25 merge, and noticed that net/9p/trans_virtio.c doesn't have a remove function. This will crash when removing the module (console doesn't have one because it can't really be removed). Signed-off-by: -

When booting from v9fs, down_interruptible in p9_idpool_get() triggered a BUG as it was being called with IRQs disabled. A spinlock seems like the right thing to be using since the idr functions go out of their way not to sleep. This patch eliminates the BUG by converting the semaphore to a spinlock. Signed-off-by:

v9fs was allowing writable mmap which could lead to kernel BUG() cases. This sets the mmap function to generic_file_readonly_mmap which (correctly) returns an error to applications which open mmap for writing. Signed-off-by: -

GDM gets unhappy if /var/gdm doesn't have the sticky bit set. This patch adds support for the sticky bit in much the same way setuid/setgid is supported. With this patch, I can launch X from a v9fs rootfs (although I quickly run out of fds in the server once gnome starts up). Signed-off-by:

Pavel Emelyanov reported that his networking card did not work and bisected it down to: " The commit 093af8d7 x86_32: trim memory by updating e820 broke my e1000 card: on loading driver says that e1000: probe of 0000:04:03.0 failed with error -5 and the interface doesn't appear. " on a 32-bit kernel, base will overflow when try to do PAGE_SHIFT, and highest_addr will always less 4G. So use pfn instead of address to avoid the overflow when more than 4g RAM is installed on a 32-bit kernel. Many thanks to Pavel Emelyanov for reporting and testing it. Bisected-by:
