This patch removes all usage of _malloc() and the function itself. Most uses are straightforward replacements by kmalloc(..., GFP_ATOMIC), because this was the definition of _malloc(). In a few places it was possible to use kzalloc() or memdup_user. A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL where possible. Verified by compilation only. Initial replacement done by running a Coccinelle script along the lines of: @@ type T; expression E; identifier V; @@ - V = (T) _malloc(E); + V = kmalloc(E, GFP_ATOMIC); @@ expression E, E1; @@ - E1 = _malloc(E); + E1 = kmalloc(E, GFP_ATOMIC); Signed-off-by: Vitaly Osipov <vitaly.osipov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
