From f4265b8d32c49ff95711e6fef7d05245a2905b30 Mon Sep 17 00:00:00 2001 From: Zhang Yi Date: Thu, 19 Jun 2025 19:18:06 +0800 Subject: ext4: add FALLOC_FL_WRITE_ZEROES support Add support for FALLOC_FL_WRITE_ZEROES if the underlying device enable the unmap write zeroes operation. This first allocates blocks as unwritten, then issues a zero command outside of the running journal handle, and finally converts them to a written state.
