Krishnasamy, Somasundaram authored
During device discovery, scsi mid layer sends INQUIRY command to LUN 0. If the LUN 0 is not mapped to host, it creates a temporary scsi_device with LUN id 0 and sends REPORT_LUNS command to it. After the REPORT_LUNS succeeds, it walks through the LUN table and adds each LUN found to sysfs. At the end of REPORT_LUNS lun table scan, it will delete the temporary scsi_device of LUN 0. When scsi devices are added to sysfs, it calls add_dev function of all the registered class interfaces. If ses driver has been registered, ses_intf_add() of ses module will be called. This function calls scsi_device_enclosure() to check the inquiry data for EncServ bit. Since inquiry was not allocated for temporary LUN 0 scsi_device, it will cause NULL pointer exception. To fix the problem, sdev->inquiry is checked for NULL before reading it. Signed-off-by:

enclosure page 7 gives us the "pretty" names of the enclosure slots. Without a page 7, we can still use the enclosure code as long as we make up numeric names for the slots. Unfortunately, the current code fails to add any devices because the check for page 10 is in the wrong place if we have no page 7. Fix it so that devices show up even if the enclosure has no page 7.

A conflict between 52c50567 ("mm: swap: unlock swapfile inode mutex before closing file on bad swapfiles") and 83ef99be ("sys_swapon: remove did_down variable") caused a double unlock of the inode mutex (once in bad_swap: before the filp_close, once at the end just before returning). The patch which added the extra unlock cleared did_down to avoid unlocking twice, but the other patch removed the did_down variable. To fix, set inode to NULL after the first unlock, since it will be used after that point only for the final unlock. While checking this patch, I found a path which could unlock without locking, in case the same inode was added as a swapfile twice. To fix, move the setting of the inode variable further down, to just before claim_swapfile, which will lock the inode before doing anything else.

Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level. Signed-off-by:

Stuart Swales authored
ADFS (FileCore) storage complies with the RISC OS filetype specification (12 bits of file type information is stored in the file load address, rather than using a file extension). The existing driver largely ignores this information and does not present it to the end user. It is desirable that stored filetypes be made visible to the end user to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu) or to a network share which can be accessed by real Acorn systems. This patch implements a per-mount filetype suffix option (use -o ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each file. This type suffix is compatible with that used by RISC OS systems that access network servers using NFS client software and by RPCemu's host filing system. Signed-off-by:

ADFS (FileCore) storage complies with the RISC OS timestamp specification (40-bit centiseconds since 01 Jan 1900 00:00:00). It is desirable that stored timestamp precision be maintained to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu). This patch implements a full-precision conversion from ADFS to Unix timestamp as the existing driver, for ease of calculation with old 32-bit compilers, uses the common trick of shifting the 40-bits representing centiseconds around into 32-bits representing seconds thereby losing precision.

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.

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:

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.
