427c3a2177eb4d34c88406bb86107548737168cc 23-Mar-2011 Ken Sumrall <ksumrall@android.com> Make a failure of the BLKDISCARD ioctl non-fatal.

Failure to erase the partition before making a new filesystem
should not be fatal, especially since this is called from recovery,
and if make_ext4fs() dies, recovery dies.

c2470654d4b4db09a7052fc5fa108ac21f1b1948 27-Jan-2011 Colin Cross <ccross@android.com> ext4_utils: Add support for wipe option, and wipe by default in recovery

Adds a -w option to make_ext4fs, which will attempt to use the
BLKSECDISCARD ioctl to erase the partition in order to avoid
leaving old data where it could be recovered, and to improve
wear levelling after a reformat.

Also causes factory reset through recovery to do a wipe.
