Subject: [PATCH 0/3] ext4: Avoid transaction stalls during writeback
Date: Tue, 11 Apr 2017 15:54:15 +0200 [thread overview]
Message-ID: <20170411135418.9638-1-jack@suse.cz> (raw)
Hello,
this series fixes stalls I've observed during a workload simulating Postgress
database. The series reduces transaction commit times about 100x in my test
setup. See patch 3/3 for more details about the workload and the results.
The series has passed testing with xfstests with 4k and 1k blocksize and
a test with 4k blocksize in dioreadnolock mode.
