The ll_rw_block() needs to get ref-count only if it submits a buffer(). This patch avoids the needless get/put of ref-count. Signed-off-by:

Change locking in the new tty buffering facility from using tty->read_lock, which is currently ignored by drivers and thus ineffective. New locking uses a new tty buffering specific lock enforced centrally in the tty buffering code. Two drivers (esp and cyclades) are updated to use the tty buffering functions instead of accessing tty buffering internals directly. This is required for the new locking to work. Minor checks for NULL buffers added to tty_prepare_flip_string/tty_prepare_flip_string_flags Signed-off-by:

The patch implements cpu topology exportation by sysfs. Items (attributes) are similar to /proc/cpuinfo. 1) /sys/devices/system/cpu/cpuX/topology/physical_package_id: represent the physical package id of cpu X; 2) /sys/devices/system/cpu/cpuX/topology/core_id: represent the cpu core id to cpu X; 3) /sys/devices/system/cpu/cpuX/topology/thread_siblings: represent the thread siblings to cpu X in the same core; 4) /sys/devices/system/cpu/cpuX/topology/core_siblings: represent the thread siblings to cpu X in the same physical package; To implement it in an architecture-neutral way, a new source file, driver/base/topology.c, is to export the 5 attributes. If one architecture wants to support this feature, it just needs to implement 4 defines, typically in file include/asm-XXX/topology.h. The 4 defines are: #define topology_physical_package_id(cpu) #define topology_core_id(cpu) #define topology_thread_siblings(cpu) #define topology_core_siblings(cpu) The type of **_id is int. The type of siblings is cpumask_t. To be consistent on all architectures, the 4 attributes should have deafult values if their values are unavailable. Below is the rule. 1) physical_package_id: If cpu has no physical package id, -1 is the default value. 2) core_id: If cpu doesn't support multi-core, its core id is 0. 3) thread_siblings: Just include itself, if the cpu doesn't support HT/multi-thread. 4) core_siblings: Just include itself, if the cpu doesn't support multi-core and HT/Multi-thread. So be careful when declaring the 4 defines in include/asm-XXX/topology.h. If an attribute isn't defined on an architecture, it won't be exported. Thank Nathan, Greg, Andi, Paul and Venki. The patch provides defines for i386/x86_64/ia64. Signed-off-by:

The implementation of int_sqrt() assumes that longs have 32 bits. On systems that have 64 bit longs this will result in gross errors when the argument to the function is greater than 2^32 - 1 on such systems. I doubt whether any such use is currently made of int_sqrt() but the attached patch fixes the problem anyway. Signed-off-by:

There is code in setfl() which attempts to preserve the O_APPEND flag on IS_APPEND files... however IS_APPEND files could also be opened O_RDONLY and in that case setfl() should not require O_APPEND... coreutils 5.93 tail -f attempts to set O_NONBLOCK even on regular files... unfortunately if you try this on an append-only log file the result is this: fcntl64(3, F_GETFL) = 0x8000 (flags O_RDONLY|O_LARGEFILE) fcntl64(3, F_SETFL, O_RDONLY|O_NONBLOCK|O_LARGEFILE) = -1 EPERM (Operation not permitted) I offer up the patch below as one way of fixing the problem... i've tested it fixes the problem with tail -f but haven't really tested beyond that. (I also reported the coreutils bug upstream... it shouldn't fail imho... <https://savannah.gnu.org/bugs/index.php?func=detailitem&item_id=15473>) Signed-off-by:

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:

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:
