You can't call module_param et al inside a function. It doesn't make sense, and it doesn't work. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Move this error-handling into a separate function so that its sizeable stack utilisation is avoided - generic_make_request() can be called recursively by stacking drivers. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Here's a patch which fixes the deadlock Brad Fitzpatrick reported here: http://lkml.org/lkml/2004/11/14/98 The meat of the problem is a locking order reversal between the XFS I/O lock and the inode semaphore (i_sem). When we mix a number of threads doing both direct reads and writes, we hit an ABBA deadlock after a while because direct-io.c is taking and dropping i_sem after the XFS read path has already taken its I/O lock. This is the wrong way around from XFS's point of view, in particular its the opposite order to the XFS write path. So this patch changes the logic for direct reads in the DIO_OWN_LOCKING case (i.e. XFS-only case), but leaves things as is for the other two types of locking. Not real pretty, but fixes up the lock ordering and deadlock. Oh, I have tested direct reads and writes on ext3 and block devices as well, to ensure they still function correctly with the change (i.e. they don't regress, should be a no-op there) which covers the other locking cases in __blockdev_direct_IO.

When cont_prepare_write() is padding out the "hole" with zeroed pages it doesn't increase i_size at the same time. If writeback comes in during the execution of cont_prepare_write(), block_write_full_page() will think that these pages are outside i_size and will just clean the page without writing it. Fix that up by using generic_commit_write(), which will advance i_size for each page as it is dirtied. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Here is a patch to update AR camera device driver. drivers/media/video/arv.c: - Remove warnings; use module_param() instead of MODULE_PARM(), because MODULE_PARM() is deprecated. - Fix white-space damages.

Vadim says: I was reading through the kernel/power/Kconfig file, and noticed that the wording was slightly unclear. I poked at it a bit, hopefully making the description a tad more straightforward, but you be the judge. :) Diffed against 2.6.10-rc2.

raid10 performs resync by reading all blocks, comparing to look for The requires re-tasking a bio that was used to read, so that it can be re-used for write. So a number of fields need to be reset. The bi_bdev field was not being reset. However when using on a partition of a device, it gets changed by generic_make_request. This patch simply resets bi_bdev to the correct value.

With Chris Wright <chrisw@osdl.org> struct task_struct.comm is defined to be 16 chars, but arch/x86_64/sys_ia32.c:sys32_ni_syscall() and sys32_vm86_warning() copy it into a static 8 byte buffer, which will surely cause problems. This patch makes lastcomm[] the right size, and makes sure it can't be overrun. Since the code also goes to the effort of getting a local copy of current in "me", we may as well use it for printing the message.

o General updates of MIPS to 2.6.10-rc2 o Remove the Baget platform due to lack of maintenance over several years. Some of the drivers remain and will be removed in a separate patch. o Remove the HP Laserjet platform. No user reports ever and no patches from the original submitters made this port a neat hack - and a directory full of clutter. o SMP support for the PMC-Sierra.

Patch from Holger Hans Peter Freyther arch/arm/mach-sa1100/KConfig had options for USB client. The related code was removed early in 2.6. releases. I think it is appropriate to remove the Config options for it itself, as they're void. Signed-off-by: Holger Hans Peter Freyther Signed-off-by: Russell King

Alternate workaround for blocking usage of select() by UDP applications. The problem is Linux optimizes the UDP receive checksum path so that checksum validation is not performed until the application read. This is a performance win but can cause applications that do select with blocking file descriptors to get false positives if the received message has a checksum error. There is a long running thread about this on LKML. This patch makes these applications work, but keeps the one-pass performance gain for those applications smart enough to use non-blocking file descriptors with select/poll. There is still a possibility to get a false positive if application does select on non-blocking fd then makes it blocking before doing the receive, but that is unlikely. Tested by injecting bad packets with SOCK_RAW. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
