Sorry for the delay on turning this around, I believe addressed the various points folks made from the last review: 1. Inode flag now correctly set when locks are held via XFS_BMAPI_RTDATA flag. 2. Realtime flag is honored when set by user via ioctl or inherit flag on directory. 3. Misc changes around formatting & bounds checks on sysfs options. See individual patches for more details. Please pay close attention to the change in xfs_file_iomap_begin (patch 2), the new version of the patch by-passes the xfs_file_iomap_begin_delay function in the "realtime" case, since the realtime code here is not reachable/dead (see assert in this function). Instead, we by-pass this, hit xfs_iomap_write_direct where the XFS_BMAPI_RTDATA will be passed on to the xfs_bmapi_write function where it's set. I'm curious if there is a better approach, and/or verification this is sane/safe.
