I am designing a file system (implemented using FUSE). I am considering enforcing exclusive locks on files while they are being written to (preventing concurrent reads). I understand that Linux is generally fine with allowing concurrent reads and writes, so I'm wondering if there are common applications or classes of applications which would break if they weren't able to read from a file that was being written to.
