Subject: [PATCH 07/32] staging: gasket: Return EBUSY on mapping create when already in use
From: Todd Poynor <toddpoynor@...gle.com>
gasket_sysfs_create_mapping() return EBUSY if sysfs mapping already in
use, as a more appropriate error code than the current return of EINVAL,
which would indicate invalid parameters.
