exFat filesystem driver seems to check a directory case sensitive and create directories case insensitive

[miracle152004]

Hi,

I am currently experiencing the following problem in calibre:
https://bugs.launchpad.net/calibre/+bug/1858425

It throws an exception if the folder name changes only by changing some of the characters, and then deletes all the files in the folder.

After reporting the issue to calibre the current working theory is, that the creation and the check is implemented differntly in the file system driver.
They first check if a directory exists and try to create it immediatly afterwards. But the creation throws an exception that the directory already exists.

The system ist running on
Ubuntu 18.04
exfat-fuse 1.2.8-1

Could you please take a look.

Thanks.

Best regards
