Subject: [PATCH] cifsd: use kfree to free memory allocated by kmalloc or kzalloc
Date: Thu, 1 Apr 2021 14:08:50 +0500	[thread overview]
Message-ID: <20210401090850.GA2779473@LEGION> (raw)

kfree should be used to free memory allocated by kmalloc or kzalloc to
avoid any overhead and for maintaining consistency.

Fixes: 5dfeb6d945 ("cifsd: use kmalloc() for small allocations")
