| * | seltests/zram: fix syntax errorZhang Zhen2015-09-152-10/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all shells define a variable UID. This is a bash and zsh feature only. In other shells, the UID variable is not defined, so here test command expands to [ != 0 ] which is a syntax error.

For example, the generic mux clock attempts to return -EINVAL, which due to the u8 return type ends up a rather large number. Using this index with the parent_names[] array results in an invalid pointer and (usually) a crash in the following strcmp(). This patch adds a check for the parent index being in range, ignoring clocks reporting invalid values.

Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions.

This hit mainline in the form of 012dcef3f058 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication.

That utility sets the block size of the device to the logical block size using the BLKBSZSET ioctl, and then issues a single sector read from the last sector of the device. This results in the dax_io code trying to do a page-sized read from 512 bytes from the end of the device. The result is -ERANGE being returned to userspace. The fix is to align the block to the page size before calling get_block. Thanks to willy for simplifying my original patch.
