    Phoronix: F2FS Will Have Faster Case-Insensitive Lookups With Linux 5.4

    The EXT4 case-insensitive lookup optimization added to the file-system with the current Linux 5.3 cycle has been ported to the Flash-Friendly File-System (F2FS) for the upcoming Linux 5.4...

    I think a lot of typical users would want to have this. It's important feature for them. "Simpler" shouldn't mean "less features".

    It's also a shitshow on OpenWrt, reliably breaking on anything that isn't x86 or ARM, and on x86 in some cases.

    This is code that does not affect most other parts of the kernel. At worst, this specific feature is bugged.

    Funny considering case insensitive is harder to implement than case sensitive. Instead of simply comparing bytes you have to take care of sensitivity. When you have a lot of alphabets (We have Unicode) it's become quite difficult. Really compare with DOS? DOS had filenames with format 8.3, supported only ANSI and wasn't case preserving. Modern implementation (like this on ext4 and F2FS) should support Unicode, be optional and case preserving. If you compare this with DOS you can also compare modern Linux with 70's UNIX.

    Another thing: Case insensitive is more natural to typical users and humans at all. Why "Letter.txt" and "letter.txt" should be different things? Why changing character case make some name totally different name? Case sensitivity forces user to think like computer do - file names is not file names but just a string of bytes. If Linux is about freedom why not give case insensitivity to user which wants it instead of trying to make him take different approach with arguments like "Its old Windows/DOS crap don't take it"?

    DOS isn't truly case-insensitive. It is always-uppercase.
