Subject[PATCH 4.14 197/267] md/raid0: Fix an error message in raid0_make_request()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit e3fc3f3d0943b126f76b8533960e4168412d9e5a ]

The first argument to WARN() is supposed to be a condition. The
original code will just print the mdname() instead of the full warning
message.

Fixes: c84a1372df92 ("md/raid0: avoid RAID0 data corruption due to layout confusion.")
