[PATCH v2 0/3] fat: add support for the renameat2 RENAME_EXCHANGE flag

by Javier Martinez Canillas

Hello, This series add support for the renameat2 system call RENAME_EXCHANGE flag (which allows to atomically replace two paths) to the vfat filesystem code. There are many use cases for this, but we are particularly interested in making possible for vfat filesystems to be part of OSTree [0] deployments. Currently OSTree relies on symbolic links to make the deployment updates an atomic transactional operation. But RENAME_EXCHANGE could be used [1] to achieve a similar level of robustness when using a vfat filesystem. Patch #1 is just a preparatory patch to introduce the RENAME_EXCHANGE support in patch #2 and finally patch #3 adds some kselftests to test it. This is a v2 that addresses issues pointed out in the first version that was posted as an RFC: https://lore.kernel.org/lkml/20220519092343.2776414-1-javierm@redhat.com/ [0]: https://github.com/ostreedev/ostree [1]: https://github.com/ostreedev/ostree/issues/1649 Changes in v2: - Only update the new_dir inode version and timestamps if != old_dir (Alex Larsson). - Add some helper functions to avoid duplicating code (OGAWA Hirofumi). - Use braces for multi-lines blocks even if are one statement (OGAWA Hirofumi). - Mention in commit message that the operation is as transactional as possible but within the vfat limitations of not having a journal (Colin Walters). - Call sync to flush the page cache before checking the file contents (Alex Larsson). - Drop RFC prefix since the patches already got some review.

[PATCH] selftest/powerpc/pmu/ebb: remove fixed_instruction.S

by Madhavan Srinivasan

Commit 3752e453f6ba ("selftests/powerpc: Add tests of PMU EBBs") added selftest testcases to verify EBB interface. instruction_count_test.c testcase needs a fixed loop function to count overhead. Instead of using the thirty_two_instruction_loop() in fixed_instruction_loop.S in ebb folder, file is linked with thirty_two_instruction_loop() in loop.S from top folder. Since fixed_instruction_loop.S not used, patch removes the file.
