Correct and simplify calculation of static rate. We need to round up the quotient of (local_rate - path_rate) / path_rate. To round up we add (path_rate - 1) to the numerator, so the quotient simplifies to (local_rate - 1) / path_rate. No idea how I came up with the old formula.

IXP2000 (ARM-based) platforms use a separate 'struct resource' for PCI MEM space. Resource allocation for PCI BARs always fails because the 'root' resource (the IXP2000 PCI MEM resource) always has the entire address space (00000000-ffffffff) free, and find_resource() calculates the size of that range as ffffffff-00000000+1=0, so all allocations fail because it thinks there is no space.

由 James Bottomley 提交于
In the new io infrastructure, all of our operators are expecting the underlying device to be little endian (because the PCI bus, their main consumer, is LE). However, there are a fair few devices and busses in the world that are actually Big Endian. There's even evidence that some of these BE bus and chip types are attached to LE systems. Thus, there's a need for a BE equivalent of our io{read,write}{16,32} operations. The attached patch adds this as io{read,write}{16,32}be. When it's in, I'll add the first consume (the 53c700 SCSI chip driver).

由 Daniel McNeil 提交于
The direct I/O code is mapping the read request to the file system block. If the file size was not on a block boundary, the result would show the the read reading past EOF. This was only happening for the AIO case. The non-AIO case truncates the result to match file size (in direct_io_worker). This patch does the same thing for the AIO case, it truncates the result to match the file size if the read reads past EOF. When I/O completes the result can be truncated to match the file size without using i_size_read(), thus the aio result now matches the number of bytes read to the end of file.

Whilst trying to stress test a Promise SX8 card, we stumbled across some nasty filesystem corruption in ext2. Our tests involved creating an ext2 partition, mounting, running several concurrent fsx's over it, umounting, and fsck'ing, all scripted[1]. The fsck would always return with errors. This regression was traced back to a change between 2.6.9 and 2.6.10, which moves the functionality of ext2_put_inode into ext2_clear_inode. The attached patch reverses this change, and eliminated the source of corruption. Mingming Cao <cmm@us.ibm.com> said: I think his patch for ext2 is correct. The corruption on ext3 is not the same issue he saw on ext2. I believe that's the race between discard reservation and reservation in-use that we already fixed it in 2.6.12- rc1. For the problem related to ext2, at the time when we design reservation for ext3, we decide we only need to discard the reservation at the last file close, so we have ext3_discard_reservation on iput_final- >ext3_clear_inode. The ext2 handle discard preallocation differently at that time, it discard the preallocation at each iput(), not in input_final(), so we think it's unnecessary to thrash it so frequently, and the right thing to do, as we did for ext3 reservation, discard preallocation on last iput(). So we moved the ext2_discard_preallocation from ext2_put_inode(0 to ext2_clear_inode. Since ext2 preallocation is doing pre-allocation on disk, so it is possible that at the unmount time, someone is still hold the reference of the inode, so the preallocation for a file is not discard yet, so we still mark those blocks allocated on disk, while they are not actually in the inode's block map, so fsck will catch/fix that error later. This is not a issue for ext3, as ext3 reservation(pre-allocation) is done in memory. Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

there seems to be a bug, at least for me, in kernel/param.c for arrays with .num == NULL. If .num == NULL, the function param_array_set() uses &.max for the call to param_array(), wich alters the .max value to the number of arguments. The result is, you can't set more array arguments as the last time you set the parameter. example: # a module 'example' with # static int array[10] = { 0, }; # module_param_array(array, int, NULL, 0644); $ insmod example.ko array=1,2,3 $ cat /sys/module/example/parameters/array 1,2,3 $ echo "4,3,2,1" > /sys/module/example/parameters/array $ dmesg | tail -n 1 kernel: array: can take only 3 arguments Signed-off-by: NBert Wesarg <wesarg@informatik.uni-halle.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

A question on sigwaitinfo based IO mechanism in multithreaded applications. I am trying to use RT signals to notify me of IO events using RT signals instead of SIGIO in a multithreaded applications. I noticed that there was some discussion on lkml during november 1999 with the subject of the discussion as "Signal driven IO". In the thread I noticed that RT signals were being delivered to the worker thread. I am running 2.6.10 kernel and I am trying to use the very same mechanism and I find that only SIGIO being propogated to the worker threads and RT signals only being propogated to the main thread and not the worker threads where I actually want them to be propogated too. On further inspection I found that the following patch which I have attached solves the problem. I am not sure if this is a bug or feature in the kernel. Roland McGrath <roland@redhat.com> said: This relates only to fcntl F_SETSIG, which is a Linux extension. So there is no POSIX issue. When changing various things like the normal SIGIO signalling to do group signals, I was concerned strictly with the POSIX semantics and generally avoided touching things in the domain of Linux inventions. That's why I didn't change this when I changed the call right next to it. There is no reason I can see that F_SETSIG-requested signals shouldn't use a group signal like normal SIGIO does. I'm happy to ACK this patch, there is nothing wrong with its change to the semantics in my book. But neither POSIX nor I care a whit what F_SETSIG does.

There is a possibility that a bio will be accessed after it has been freed on SCSI. It happens if you submit a bio with BIO_SYNC marked and the auto-unplugging kicks the request_fn, SCSI re-enables interrupts in-between so if the request completes between the add_request() in __make_request() and the bio_sync() call, we could be looking at a dead bio. It's a slim race, but it has been triggered in the Real World. So assign bio_sync() to a local variable instead.
