Currently we only print the default io scheduler if the kernel chooses, not if the user/bootloader has specified one. This patch saves the extra line in dmesg but always notified of the default choice by appending (default) to that line: .. io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered (default) .. Patch originally from Srihari Vijayaraghavan, modified by me. Signed-off-by:

The accounting can go bad in the requeue hook, it must check the accounted flag to make sure it was previously considered in the driver. Signed-off-by:

This apparently explains some weird IO failures reported in last two months. Only non-bwx (including generic) kernels were affected. Acked-by:

This enables it only for debug kernels, and also makes sure that if some external module is still broken, we don't leave the mmap-sem locked after warning about it.

It seems to be general consensus that its safer to require all do_brk() callers to grab mmap_sem, and have do_brk to warn otherwise. This is what the following patch does. Similar version has been changed to in v2.4. Signed-off-by: -

We had all the locking right, but we didn't check whether one of the threads now no longer needed to expand, so we could incorrectly _shrink_ the stack in the other thread instead (not only causing segfaults, but since we didn't do a proper unmap, we'd possibly leak pages too). So re-check the need for expand after getting the lock. Noticed by Paul Starzetz.

Fix fallout from the recent nodemask_t changes. The node ids assigned in the SRAT parser were off by one. I added a new first_unset_node() function to nodemask.h to allocate IDs sanely. Signed-off-by:

I found bugs on error handlings in the functions arround the ext3 file system, which cause inadequate completions of synchronous write I/O operations when disk I/O failures occur. Both 2.4 and 2.6 have this problem. I carried out following experiment: 1. Mount a ext3 file system on a SCSI disk with ordered mode. 2. Open a file on the file system with O_SYNC|O_RDWR|O_TRUNC|O_CREAT flag. 3. Write 512 bytes data to the file by calling write() every 5 seconds, and examine return values from the syscall. from write(). 4. Disconnect the SCSI cable, and examine messages from the kernel. After the SCSI cable is disconnected, write() must fail. But the result was different: write() succeeded for a while even though messages of the kernel notified SCSI I/O error. By applying following modifications, the above problem was solved. Signed-off-by:Hisashi Hifumi <hifumi.hisashi@lab.ntt.co.jp> Signed-off-by:

From: Manfred Spraul One bios assigns a small window for i/o access to yenta bridges. But there are Cardbus cards that needs lots of i/o ports. yenta usually honors the bios selected values, except if the bios choice is clearly invalid. The patch allows an override from the command line. Signed-Off-By:

validate_mem() does only make sense for !SS_CAP_STATIC_MAP sockets. Therefore, re-direct validate_mem() calls only for those. The newly added redirection layer will allow for a "library" module named "rsrc_nonstatic" which contains the resource database handling code, and it will only need to be loaded for the drivers which need it.

Make the io and mem db per-socket, as different sockets may have different requirements or may not even need the resource db at all (SS_CAP_STATIC_MAP). Updated to make rsrc_mem_probe per-socket and to remove unnecessary and even broken check for empty list as per Russell King's suggestions. Signed-off-by:

Instead of "memory_cs", BIND_MTD, {FIRST,NEXT}_REGION, 2.6. kernels use the "pcmciamtd" driver which doesn't need these functions. Cardmgr still calls it in default configuration, so warn the user about changes necessary to /etc/pcmcia/config , and remove the now unused code. Signed-off-by: -

Remove the "Attributes" entry of struct client_t -- _all_ in-kernel drivers did set it to INFO_IO_CLIENT | INFO_CARD_SHARE anyway, and the pcmcia core didn't care at all what this value was set to. Also, remove the setting of the respective request field in all in-kernel drivers -- the request structure is kept the same, though, to keep external drivers compiling. Signed-off-by:
