Doing experimentation recently to Samba, seems like the following is a minimal regression test bucket for cifs.ko (assuming 3.0 dialect, minimal server features) regression testing. It includes 70 tests. To local host it took just under 6 minutes to run to Samba using recent for-next branch for the cifs.ko client. How does this compare with other's xfstest buckets for cifs.ko. More tests would run to windows, and more would run e.g. if I turned on optional features (e.g. vfs_btrfs and thus reflink support) - but this is a good set - 70 tests, and avoids the long xfstests, the many skips, and the xfstest failures (many of which need active investigation ASAP) ./check -cifs cifs/001 generic/001 generic/002 generic/005 generic/006 generic/007 generic/011 generic/013 generic/014 generic/020 generic/023 generic/024 generic/028 generic/029 generic/030 generic/036 generic/037 generic/069 generic/070 generic/074 generic/075 generic/080 generic/084 generic/091 generic/095 generic/098 generic/100 generic/109 generic/112 generic/113 generic/117 generic/124 generic/129 generic/130 generic/132 generic/133 generic/135 generic/141 generic/169 generic/198 generic/207 generic/210 generic/211 generic/212 generic/215 generic/221 generic/239 generic/245 generic/246 generic/247 generic/248 generic/249 generic/257 generic/263 generic/285 generic/286 generic/308 generic/309 generic/315 generic/337 generic/340 generic/344 generic/345 generic/346 generic/354 generic/360 generic/393 generic/394 generic/406 generic/412 -- Thanks, Steve
