Package: src:linux
Version: 4.3.5-1
Severity: normal
{ Not sure if this is the right package to report this bug against;
please move appropriately, if necessary. }
Symptoms
--------
When mounting a FAT32, FAT16, or FAT12 file system with the option
"shortname=lower" and creating a directory with an all-uppercase name,
the directory cannot be removed afterwards, neither by "rm -r" nor
"rmdir".
Note that otherwise, accessibility of the directory is not affected;
one can cd to it, and access files below it without problems.
Mount version used: 2.27.1-6.
Mount options
shortname=win95
shortname=winnt
shortname=mixed
do not show this behavior.
Steps to reproduce
