[PATCH 4.14 197/267] md/raid0: Fix an error message in raid0_make_request()

From: Greg Kroah-Hartman
Date: Mon Dec 16 2019 - 12:58:35 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ 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.")
