IIRC a few of them > depend on the fs supporting fileattr_get Thanks for the Ack. I checked the current xfstests tree and couldn=E2=80=99t find a test tha= t flips from notrun to run on cifs just from adding ->fileattr_get. generic/556 is the existing case-folding test, but _has_casefold_kernel_support in common/casefold hard-codes ext4/f2fs/tmpfs. Enabling it on cifs would need a new mechanism in common/casefold plus a mount-option-driven variant (the cifs reporting keys off nocase, not a per-inode flag), so that's a separate piece of work. The practical effect on the existing suite is that fsstress's getattr_f now returns success instead of ENOTTY on cifs, which quiets some noise but doesn't gate any test. To actually exercise the new FS_XFLAG_CASEFOLD reporting I think a new test (or a generalization of generic/556) would have to be written. --=20 Chuck Lever
