Currently, if you open a file O_DIRECT, truncate it to a size that is not a multiple of the disk block size, and then try to read the last block in the file, the read will return 0. The problem is in do_direct_IO, here: /* Handle holes */ if (!buffer_mapped(map_bh)) { char *kaddr; ... if (dio->block_in_file >= i_size_read(dio->inode)>>blkbits) { /* We hit eof */ page_cache_release(page); goto out; } We shift off any remaining bytes in the final block of the I/O, resulting in a 0-sized read. I've attached a patch that fixes this. I'm not happy about how ugly the math is getting, so suggestions are more than welcome. I've tested this with a simple program that performs the steps outlined for reproducing the problem above. Without the patch, we get a 0-sized result from read. With the patch, we get the correct return value from the short read.

When v9fs_mux_rpc sends a 9P message, it may be put in the queue of unsent request. If the user process receives a signal, v9fs_mux_rpc sets the request error to ERREQFLUSH and assigns NULL to request's send message. If the message was still in the unsent queue, v9fs_write_work would produce an oops while processing it. The patch makes sure that requests that are being flushed are moved to the pending requests queue safely. If a request is being flushed, don't remove it from the list of pending requests even if it receives a reply before the flush is acknoledged. The request will be removed during from the Rflush handler (v9fs_mux_flush_cb). Signed-off-by:

Add support for the built-in parallel port on SGI O2 (a.k.a. IP32). Define a new configuration option: PARPORT_IP32. The module is named parport_ip32. Hardware support for SPP, EPP and ECP modes along with DMA support when available are currently implemented. Signed-off-by:

Fix the problem in kernel 2.6.15.1 (and early versions) that OProfile on x86_64 does not correctly collect the stack traces for kernel functions. The original code in valid_kernel_stack() in arch/i386/oprofile/backtrace.c assumes that the frame pointer (headaddr) should be greater than stack (i.e., regs). This assumption is wrong for x86_64 because NMIs in x86_64 use a seperate stack different from the kernel stack. Therefore, the variable stack now points to some location on the NMI stack, which turns out to be at a higher address than the frame pointer (headaddr) on the kernel stack. The correct comparison here should be between headaddr and regs->rsp for x86_64. Signed-off-by:

This fixes the code like this: bh = sb_find_get_block (sb, tmp + j); if ((bh && DATA_BUFFER_USED(bh)) || tmp != fs32_to_cpu(sb, *p)) { retry = 1; brelse (bh); goto next1; } bforget (bh); sb_find_get_block() ordinarily returns a buffer_head with b_count>=2, and this code assume that in case if "b_count>1" buffer is used, so this caused infinite loop. (akpm: that is-the-buffer-busy code is incomprehensible. Good riddance. Use of block_truncate_page() seems sane). Signed-off-by:Evgeniy Dushistov <dushistov@mail.ru> Signed-off-by:

"rm" command, on file system with "ufs1" type cause system hang up. This is, in fact, not so bad as it seems to be, because of after that in "kernel control path" there are 3-4 places which may cause "oops". So the first patch fix oopses, and the second patch fix "kernel hang up". "oops" appears because of reading of group's summary info partly wrong, and access to not first group's summary info cause "oops". Signed-off-by:

When one module exports a function symbol and another module uses that symbol then kallsyms shows the symbol twice. Once from the consumer with a type of 'U' and once from the provider with a type of 't' or 'T'. On most architectures, both entries have the same address so it does not matter which one is returned by kallsyms_lookup_name(). But on architectures with function descriptors, the 'U' entry points to the descriptor, not to the code body, which is not what we want. IA64 # grep -w qla2x00_remove_one /proc/kallsyms a000000208c25ef8 U qla2x00_remove_one [qla2300] <= descriptor a000000208bf44c0 t qla2x00_remove_one [qla2xxx] <= function body Tell kallsyms_lookup_name() to ignore type U entries in modules.
