Subject: [PATCH 08/17] f2fs: remove FAULT_ALLOC_BIO
Date: Tue, 26 Jan 2021 15:52:38 +0100
Message-ID: <20210126145247.1964410-9-hch@lst.de> (raw)
In-Reply-To: <20210126145247.1964410-1-hch@lst.de>

Sleeping bio allocations do not fail, which means that injecting an error
into sleeping bio allocations is a little silly.
