Kernel crashes in fs/adfs module when accessing directories with a large number of objects on mounted Acorn ADFS E+/F+ format discs (or images) as the existing code writes off the end of the fixed array of struct buffer_head pointers. Additionally, each directory access that didn't crash would leak a buffer as nr_buffers was not adjusted correctly for E+/F+ discs (was always left as one less than required). The patch fixes this by allocating a dynamically-sized set of struct buffer_head pointers if necessary for the E+/F+ case (many directories still do in fact fit in 2048 bytes) and sets the correct nr_buffers so that all buffers are released. Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26072 Tested by tar'ing the contents of my RISC PC's E+ format 20Gb HDD which contains a number of large directories that previously crashed the kernel.

page-types.c doesn't supply a way to specify the debugfs path and the original debugfs path is not usual on most machines. This patch supplies a way to auto mount debugfs if needed.

I noticed the 'mcelog' program had no comment and then ended up "fixing" a few more things: * reiserfsck -V does not print "reiserfsprogs" (any more?) * is "udevinfo" still shipped? udevd certainly is * grub2 doesn't have a 'grub' binary * add a "# how to get the mcelog version" comment Signed-off-by:

There is a missing case for "Chapter 3: Placing Braces and Spaces". We often know we should not use braces where a single statement. The first case is: if (condition) action(); Another case is: if (condition) do_this(); else do_that(); However, I can not find a description of the second case. Signed-off-by:

Not all 64-bit systems require ISA-style DMA, so allow it to be configurable. x86 utilizes the generic ISA DMA allocator from kernel/dma.c, so require it only when CONFIG_ISA_DMA_API is enabled. Disabling CONFIG_ISA_DMA_API is dependent on x86_64 since those machines do not have ISA slots and benefit the most from disabling the option (and on CONFIG_EXPERT as required by H. Peter Anvin). When disabled, this also avoids declaring claim_dma_lock(), release_dma_lock(), request_dma(), and free_dma() since those interfaces will no longer be provided. Signed-off-by:

The generic floppy disk driver utilizies the interface provided by CONFIG_ISA_DMA_API, specifically claim_dma_lock(), release_dma_lock(), request_dma(), and free_dma(). Thus, there's a strict dependency on the config option and the driver should only be loaded if the kernel supports ISA-style DMA. Signed-off-by:

IORESOURCE_DMA cannot be assigned without utilizing the interface provided by CONFIG_ISA_DMA_API, specifically request_dma() and free_dma(). Thus, there's a strict dependency on the config option and limits IORESOURCE_DMA only to architectures that support ISA-style DMA. ia64 is not one of those architectures, so pnp_check_dma() no longer needs to be special-cased for that architecture. pnp_assign_resources() will now return -EINVAL if IORESOURCE_DMA is attempted on such a kernel.

If you run checkpatch against multiple patches, and one of them has a whitespace issue which can be helped via a script (rpt_cleaners), you will see the same NOTE over and over for all subsequent patches. It makes it seem like those patches also have whitespace problems when in reality, there's only one or two bad apples. So reset rpt_cleaners back to 0 after we've issued the note so that it only shows up near the patch with the actual problems. Signed-off-by:

1. simple_strto*() do not contain overflow checks and crufty, libc way to indicate failure. 2. strict_strto*() also do not have overflow checks but the name and comments pretend they do. 3. Both families have only "long long" and "long" variants, but users want strtou8() 4. Both "simple" and "strict" prefixes are wrong: Simple doesn't exactly say what's so simple, strict should not exist because conversion should be strict by default. The solution is to use "k" prefix and add convertors for more types. Enter kstrtoull() kstrtoll() kstrtoul() kstrtol() kstrtouint() kstrtoint() kstrtou64() kstrtos64() kstrtou32() kstrtos32() kstrtou16() kstrtos16() kstrtou8() kstrtos8() Include runtime testsuite (somewhat incomplete) as well. strict_strto*() become deprecated, stubbed to kstrto*() and eventually will be removed altogether. Use kstrto*() in code today! Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if they'll be unused at runtime. This is temporarily solution, because I don't want to hardcode list of archs where these functions aren't needed. Current solution with sizeof() and __alignof__ at least always works. Signed-off-by:
