Subject: test/libcephfs: test getcwd with case insensitive dir
X-Git-Tag: testing/wip-rishabh-testing-20250315.120910-debug~15^2~3
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=28bdb8e565f0b6b3090808f4759c70693d92eb05;p=ceph-ci.git

test/libcephfs: test getcwd with case insensitive dir

Unfortunately, it's not easy to refactor this test into a shared method without
setting up an explicit test class which has been avoided up to this point. So
I'm going to just copy the code. Sorry.
