I just read the man page that had discard mount. That is a Linuxism. I
think you are asking about TRIM support. As both native file systems
already have TRIM support and the ext driver is ext2 and is mostly just
used to move files from/to Linux, I have not seen any plans to add any of
the ext4 features to the base OS. Unless you require the ability to read
the file system from both Linux and FreeBSD, ext2 is a rather dated file
system and should not be used in FreeBSD.
Are there any plans to implement ext4 in FreeBSD? Would there be license
