block: remove CONFIG_LBDAF

2019-04-06T16:48:35Z

Currently support for 64-bit sector_t and blkcnt_t is optional on 32-bit architectures. These types are required to support block device and/or file sizes larger than 2 TiB, and have generally defaulted to on for a long time. Enabling the option only increases the i386 tinyconfig size by 145 bytes, and many data structures already always use 64-bit values for their in-core and on-disk data structures anyway, so there should not be a large change in dynamic memory usage either. Dropping this option removes a somewhat weird non-default config that has cause various bugs or compiler warnings when actually used. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

torture: Suppress false-positive CONFIG_INITRAMFS_SOURCE complaint

2019-03-26T21:42:53Z

The scripting must supply the CONFIG_INITRAMFS_SOURCE Kconfig option so that kbuild can find the desired initrd, but the configcheck.sh script gets confused by this option because it takes a string instead of the expected y/n/m. This causes checkconfig.sh to complain about CONFIG_INITRAMFS_SOURCE in the torture-test output (though not in the summary). As more people use rcutorture, the resulting confusion is an increasing concern. This commit therefore suppresses this false-positive warning by filtering CONFIG_INITRAMFS_SOURCE from within the checkconfig.sh script. Reported-by: Joel Fernandes Signed-off-by: Paul E. McKenney

tools/.../rcutorture: Convert to SPDX license identifier

2019-03-26T21:42:53Z

Replace the license boiler plate with a SPDX license identifier. While in the area, update an email address and add copyright notices. Signed-off-by: Paul E. McKenney

tools headers: Move the nolibc header from rcutorture to tools/include/nolibc/

2019-01-25T23:37:13Z

As suggested by Ingo, this header file might benefit other tools than just rcutorture. For now it's quite limited, but is easy to extend, so exposing it into tools/include/nolibc/ will make it much easier to adopt by other tools. The mkinitrd.sh script in rcutorture was updated to use this new location. Cc: Ingo Molnar Cc: Arnaldo Carvalho de Melo Cc: Paul E. McKenney Signed-off-by: Willy Tarreau Signed-off-by: Paul E.

rcutorture/nolibc: Add a bit of documentation to explain how to use nolibc

2019-01-25T23:37:13Z

Ingo rightfully asked for a bit more documentation in the nolibc header, so this patch adds some explanation about its purpose, how it's made, and how to use it. Cc: Ingo Molnar Cc: Paul E.

rcutorture/nolibc: Fix some poor indentation and alignment

2019-01-25T23:37:12Z

A few macros had their rightmost backslash misaligned, and the pollfd struct definition resisted the previous code reindent. Nothing else changed. Cc: Paul E. McKenney Signed-off-by: Willy Tarreau Signed-off-by: Paul E. McKenney Reviewed-by: Joey Pabalinas

rcutorture/nolibc: Fix the clobbered registers in the MIPS syscall definition

2019-01-25T23:37:11Z

A last-minute checkpatch cleanup caused most of list of clobbered registers to be lost in the MIPS syscall definition. Although this code is not yet used on MIPS, it is nevertheless better to fix it before it does get used. Cc: Paul E. McKenney Signed-off-by: Willy Tarreau Signed-off-by: Paul E. McKenney

torture: Explain and simplify odd "for" loop in mkinitrd.sh

2019-01-25T23:37:09Z

Why a Bourne-shell "for" loop? And why 192 instances of "a"? This commit adds a shell comment to present the answer to these mysteries. It also uses a series of factor-of-four Bourne-shell assignments to make it easy to see how many instances there are, replacing the earlier wall of 'a' characters.
