Hi. Currently "commit" for ext3 documented so:

.BI commit= nrsec
Sync all data and metadata every
.I nrsec
seconds.  The default value is 5 seconds.  Zero means default.

And in the beginning of ext4:

The options
.B journal_dev, norecovery, noload, data, commit, orlov, oldalloc, [no]user_xattr
.B [no]acl, bsddf, minixdf, debug, errors, data_err, grpid, bsdgroups, nogrpid
.B sysvgroups, resgid, resuid, sb, quota, noquota, grpquota, usrquota
.B usrjquota, grpjquota and jqfmt
are backwardly compatible with ext3 or ext2.

So, it seems from man that ext4 has same "commit" option and its default value is 5 seconds (even if I don't specify "commit" at command line at all). But it seems that this is wrong ( https://lwn.net/Articles/322823/ ). So, please, fix the man

We use kernel docs as the source :-) I'll ask extN developers for the help. Thanks.

Note, I have removed extN from mount.8. The extN mount options will not be maintained by util-linux any more. You have to use "man ext4" (from e2fsprogs).
