What is the modified value? You might as well say that fitrim will adjust the minimum if it's smaller than the device's minimum, and report that back to userspace. > By increasing this value, the fstrim operation will complete > +more quickly for filesystems with badly fragmented freespace, although not > +all blocks will be discarded. The default value is zero, discarding every free block. I prefer the practice of starting each sentence in the manpage source on a new line so that the diff only reflects changes to actual content (and not just reflowing of the text)... but the sys-utils maintainers clearly don't employ that convention so I guess this is ok. :) Thanks for putting together the documentation update.
