307inlinecrypt When possible, encrypt/decrypt the contents of encrypted
308 files using the blk-crypto framework rather than
309 filesystem-layer encryption. This allows the use of
310 inline encryption hardware. The on-disk format is

315discard_unit=%s Control discard unit, the argument can be "block", "segment"
316 and "section", issued discard command's offset/size will be
317 aligned to the unit, by default, "discard_unit=block" is set,
318 so that small discard functionality is enabled.
319 For blkzoned device, "discard_unit=section" will be set by
320 default, it is helpful for large sized SMR or ZNS devices to
321 reduce memory cost by getting rid of fs metadata supports small
322 discard.
