Hi all, The first patch provides a second regression test for a condition where mmap read of a file's EOF page shows nonzero bytes after EOF if the previous operation was a zero_range all the way to EOF. This bug only seems to manifest on XFS, but it uses generic APIs and so is a generic test. The patch concerned here is "xfs: ensure post-EOF zeroing happens after zeroing part of a file". The second patch adds tests to see if XFS can detect and correct incorrect filesystem summary counters at mount time. Patch 3-5 fix some minor problems that cropped up with the upcoming xfsprogs 4.19 release due to stricter metadata verification. Patch 6 adds some regression tests for incorrect behavior on the part of the clonerange and deduperange ioctls. Specifically, we check for a lack of file range verification w.r.t. resource limits; lack of security privilege clearing when a file is reflinked; exposure of stale disk contents when a file is reflinked into well above EOF; and problems deduping when a single byte in the middle of the range doesn't match. --D
