Signed-off-by: Namjae Jeon <namjae.jeon@...sung.com> Signed-off-by: Ashish Sangwan <a.sangwan@...sung.com> Reviewed-by: Brian Foster <bfoster@...hat.com> --- Changelog v9: - check that mkfs and mount succeed. - check extent_before and extent_after instead of hardcode 1. - remove umount. v8: - use MKFS_OPTION to use blocksize in configuration and remove loop. - remove trailing space. - compare original file and test file to check data integrity. tests/generic/043 | 96 +++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/043.out | 2 ++ tests/generic/group | 1 + 3 files changed, 99 insertions(+) create mode 100644 tests/generic/043 create mode 100644 tests/generic/043.out diff --git a/tests/generic/043 b/tests/generic/043 new file mode 100644 index 0000000..a6f91ce --- /dev/null +++ b/tests/generic/043 @@ -0,0 +1,96 @@ +#! /bin/bash +# FS QA Test No. generic/043 +# +# Test multiple fallocate insert/collapse range calls on same file. +# Call insert range a single alternate block multiple times until the file +# is left with 100 extents and as much number of extents.
