[PATCH v2 0/3] fs_parser: handle parameters that can be empty and don't have a value

While investigating an ext4/053 fstest failure, I realised that there was
an issue when the flag 'fs_param_can_be_empty' is set in a parameter and it
doesn't have a value

After an initial attempt to fix the issue, Christian suggested a different
approach and the following patches are based in his suggestion.

Another change that I'm introducing in this v2 is the change of parameter
'test_dummy_encryption' to also use the new helper introduced by the first
patch in this series.

Finally, I'd like to ask someone to look closer at the overlayfs patch as
I don't think there were any fstests to validate the case where 'lowerdir'
is empty.

Luis Henriques (3):
fs_parser: add helper to define parameters with string and flag types
ext4: fix the parsing of empty string mount parameters
ovl: fix the parsing of empty string mount parameters
