[fedora-arm] [Fwd: discard support in e2fsprogs and dm]

[Jon Masters]

Folks,

In case anyone is interested, I have Fedora running on the AC100U now.
Unlike some of the other hacks I've seen I wanted to actually use the
storage efficiently with device mapper presenting it as a contig. block
device. Unfortunately, some of the block discard support seems to be
tripping that up. If you try an AC100 with dm, make sure you specify "-E
nodiscard" to mkfs.ext4 during filesystem creation.

Jon.
