From dcd6158d15c7a57d448103e1d51dac5e1a19a406 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 18 Oct 2019 16:41:12 -0700 Subject: [PATCH] iomap: always use AOP_FLAG_NOFS in iomap_write_begin All callers pass AOP_FLAG_NOFS, so lift that flag to iomap_write_begin to allow reusing the flags arguments for an internal flags namespace soon. Also remove the local index variable that is only used once. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
