The patchset also added new error injection tags for, 1. Reducing maximum extent count to 10. 2. Allocating only single block sized extents. The corresponding code for xfsprogs can be obtained from https://lore.kernel.org/linux-xfs/20201104114900.172147-1-chandanrlinux@gmail.com/. The patches posted along with this cover letter add tests to verify the correctness of in-kernel inode extent count overflow detection mechanism. These patches can also be obtained from https://github.com/chandanr/xfstests.git at branch extent-overflow-tests. Changelog: V2 -> V3: 1. Kernel's max pseudo extent count is once again set to 10. Hence change the tests back to using 10 as the maximum extent count. 2. The following tests associated with directories have been removed since directory remove and rename operations are not expected to fail (with -EFBIG error code) in low inode extent count scenarios: - Populate source directory and mv one entry to destination directory. - Populate a directory and remove one entry. V1 -> V2: 1. Obtain extent count for inodes accessible through filesystem path names via "xfs_io -c 'stat' ..." command line. This gets rid of unmount/mount cycles from most of the tests. 2. Use _fill_fs() to consume free space of a filesystem. 3. Use _scratch_inject_error() helper to enable/disable error tags. 4. Use sizeof(struct xfs_dqblk) to calculate number of quotas inside one filesystem block. 5. Write once to every block of the quota inode instead of sequentially filling up each block. 6. Use _get_file_block_size() for tests involving regular files. 7. Modify tests to suit the new pseudo max extent count of 35. 8. Replace xfs_io with $XFS_IO_PROG. 9. Remove code that extended a realtime file since this takes the same path as direct I/O to a regular file. 10. For xattr, do not execute test script when block size is < 4k. 11. Add code to test if removing an xattr from a full attribute fork succeeds. 12. Add code to test if removing a file whose attribute fork is full succeeds. 13. Add code to test if removing a entry from a full directory succeeds. 14. Add code to test if removing a full directory succeeds. 15. Writing to unwritten extents: Integrate buffered and direct I/O tests into a for loop. 16. Writing to a shared extent test: Add test to check funshare operation. 17. Use _scale_fsstress_args() to scale values for "-p" and "-n" arguments for fsstress.
