The XFS file-system improvements merged for Linux 7.3 add support for FALLOC_FL_WRITE_ZEROES for end-users.
The feature provides an efficiency improvement for XFS by enabling zero-filled allocations via the fallocate system call. This can reduce the amount of data written when pre-allocating space, benefiting storage workloads that rely on XFS. The change is specific to the Linux 7.3 kernel release.
