Make it less confusing when, for example, stat sets errno to 122 because a checksum failed in ZFS: Before: getfacl: /foo/bar: stat() failed: Unknown error: 122 After: getfacl: /foo/bar: stat() failed: Integrity check failed Submitted by: Ryan Moeller <ryan@ixsystems.com> Modified: stable/12/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h Directory Properties: stable/12/ (props changed) Modified: stable/12/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h ============================================================================== --- stable/12/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h Thu Jan 30 16:11:19 2020 (r357296) +++ stable/12/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h Thu Jan 30 16:38:40 2020 (r357297) @@ -227,12 +227,11 @@ enum zio_wait_type { }; /* - * We'll take the number 122 and 123 to indicate checksum errors and - * fragmentation.
