Please review when you free, thank! Changes v2 -> v3: Patch 1: - update the commit title and commit message. [Andra] - use 'struct range' to instead of 'struct phys_mem_region'. [Andra, Greg KH] - add comments before the function definition. [Andra] - rename several variables, parameters and function. [Andra] Patch 2: - update the commit title and commit message. [Andra] - add comments before the function definition. [Andra] - remove 'inline' attribute of ne_sanity_check_phys_mem_region. [Andra] - leave a blank line before return. [Andra] - move sanity check in ne_merge_phys_contig_memory_regions to the beginning of the function. [Andra] - double sanity checking after the merge of physical contiguous memory regions has been completed. [Andra] Patch 3: - update the commit title and commit message. [Andra] - use "misc_dev"/"misc device"/"MISC_DEV" to be more specific. [Andra] Patch 4: - update the commit title and commit message. [Andra] - align the fileds in 'struct phys_regions_test'. [Andra] - rename 'phys_regions_testcases' to 'phys_regions_test_cases'. [Andra] - add comments before each test cases. [Andra] - initialize the variables in ne_misc_dev_test_merge_phys_contig_memory_regions. [Andra] Changes v1 -> v2: - update the commit message as Andra's suggestion [Andra] - remove TODO completely in ne_set_user_memory_region_ioctl [Andra] - extract the physical memory regions setup into individual function - add kunit tests [Andra] Longpeng (4): nitro_enclaves: Merge contiguous physical memory regions nitro_enclaves: Sanity check physical memory regions during merging nitro_enclaves: Add KUnit tests setup for the misc device functionality nitro_enclaves: Add KUnit tests for contiguous physical memory regions merging drivers/virt/nitro_enclaves/Kconfig | 9 ++ drivers/virt/nitro_enclaves/ne_misc_dev.c | 163 +++++++++++++++++++------ drivers/virt/nitro_enclaves/ne_misc_dev_test.c | 153 +++++++++++++++++++++++ 3 files changed, 285 insertions(+), 40 deletions(-) create mode 100644 drivers/virt/nitro_enclaves/ne_misc_dev_test.c -- 1.8.3.1
