- * of chattr/lsattr (which was shipped as part of e2fsprogs). You

- *
- * We have recently hoisted FS_IOC_FSGETXATTR / FS_IOC_FSSETXATTR from
- * XFS to the generic FS level interface. This uses a structure that
- * has padding and hence has more room to grow, so it may be more
- * appropriate for many new use cases.
