 improvement



Hello,

kernel test robot noticed a 249.0% improvement of aim7.jobs-per-min on:


commit: 03de20bed203b0819225d4de98353c1f8755a1dd ("ext4: do not mark inode dirty every time when appending using delalloc")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: aim7
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:

	disk: 1BRD_48G
	fs: ext4
	test: disk_cp
	load: 3000
	cpufreq_governor: performance


In addition to that, the commit also has significant impact on the following tests:
