et4: allow zeroout when doing written to unwritten split (2026-01-23 16:50:11 -0500)
----------------------------------------------------------------
New features and improvements for the ext4 file system
* Avoid unnecessary cache invadiation in the extent status cache
(es_cache) when adding extents to be cached in the es_cache and we
are not changing the extent tree.
* Add a sysfs parameter, err_report_sec, to control how frequently
to log a warning message that file system inconsistency has been
detected. (Previously we logged the warning message every 24
hours.)
* Avoid unnecessary forced ordered writes when appending to a file
when delayed allocation is enabled.
* Defer splitting unwritten extents to I/O completion to improve
write performance of concurrent direct I/O writes to multiple
files.
* Refactor and add kunit tests to the extent splitting and
conversion code paths.
Various Bug Fixes
* Fix a panic when the debugging DOUBLE_CHECK macro is defined.
* Avoid using fast commit for rare and complex file system
operations to make fast commit easier to reason about. This can
also avoid some corner cases that could result in file system
inconsistency if there is a crash between the fast commit before a
subsequent full commit.
* Fix memory leaks in error paths
* Fix a false positive reports caused when running stress tests
using mixed huge-page workloads caused by a race between page
migration and bitmap updates.
* Fix a potential recursion into file system reclaim when evicting
an inode when fast commit is enabled.
* Fix a warning caused by a potential double decrement to the dirty
clusters counter when executing FS_IOC_SHUTDOWN when running a
stress test.
* Enable mballoc optimzied scanning regardless whether the inode is
using indirect blocks or extent trees to map blocks.
