Trying to work with the tests

[Ian Kent]

I'm new to the list so Hi to all,


I'm working with a heavily patched 5.14 kernel and I've gathered 
together patches to bring erofs

up to 5.19 and I'm trying to run the erofs and fscache tests from a 
checkout of the 1.7.1 repo.

(branch experimental-tests-fscache) and I have a couple of fails I can't 
quite work out so I'm

hoping for a little halp.


For those familiar with erofs development and history it may look like 
some patches are missing

but they may have already been present in the source tree I'm working 
with ... so just ask if

you spot anything ...


Current set of patches I have is (the patch name corresponds to commit 
title, more or less):

The last patch consists of what looks like a few hunks added by Linus to 
complete a folio pull

request that came in at the same time as the 5.19 erofs merge request. I 
know the list of

patches isn't very useful but it should give some idea of what I have 
and maybe someone can

spot a missing patch or so.


Anyway, my failing tests are erofs/021, erofs/022, erofs/024 and 
fscache/005.

erofs/018 does not run due to "lzma compression is disabled, skipped." 
message which I think

is too old a version of xz.


Any insight into cases that could cause these tests to fail would be 
much appreciated.
