$ pwd
/home/projects/util-linux
$ findmnt --target .
TARGET SOURCE FSTYPE OPTIONS
/home /dev/nvme0n1p2 ext4 rw,relatime
man page:
-T, --target path
Define the mount target. If path is not a mountpoint
file or directory, then findmnt checks the path elements
in reverse order to get the mountpoint (this feature is
supported only when searching in kernel files and
unsup‐ ported for --fstab). It's recommended to use
the option --mountpoint when checks of path elements are
unwanted and path is a strictly specified mountpoint.
I'll prove the beginning of the man page to make this feature more
obvious.
