Deleted directory path not recorded when running rmdir with slash at directory path end

[Alan Evangelista]

If I run the rmdir command with a directory path with a slash at its end,
Audit doesn't record the deleted directory path.

Audit rule:
-a always,exit -F dir=/sasdata -F arch=b64 -S creat -S open -S openat -S
unlink -S unlinkat -S symlink -S symlinkat -S link -S linkat -S rename -S
renameat -S chmod -S fchmod -S fchmodat -S chown -S fchown -S fchownat -S
mkdir -S mkdirat -S rmdir -S setxattr -S lsetxattr -S fsetxattr -S
removexattr -S lremovexattr -S fremovexattr -k filesystem_op

Test command:
rmdir /sasdata/testdir

Audit output:

Shouldn't the directory path be recorded somewhere, regardless if there is
a slash at the end of the directory path?

I found this issue while using Auditbeat, a collector of Linux Audit events
used for integration with Elasticsearch. Related discussion:

Thanks in advance.
