Hello, It looks like the fix b5776e7524afbd4569978ff790864755c438bba7 "ext4: fix potential htree index checksum corruption” introduced this regression. I reverted it and my test from previous message passed the dangerous level of 1570000 names count. Now test is still in progress. 2520000 names are already created. I am searching the way to fix this. Best regards, Artem Blagodarenko. > On 22 Jul 2021, at 17:23, Carlos Carvalho <carlos@xxxxxxxxxxxxxx> wrote: > > There is a bug when enabling large_dir in 5.12.17.
