Btrfs: create a pinned em when writing to a prealloc range in DIO Wade Cline reported a problem where he was getting garbage and warnings when writing to a preallocated range via O_DIRECT. This is because we weren't creating our normal pinned extent_map for the range we were writing to, which was causing all sorts of issues. This patch fixes the problem and makes his testcase much happier. Thanks, Reported-by: Wade Cline <clinew@linux.vnet.ibm.com> Signed-off-by: Josef Bacik <jbacik@fusionio.com>
