[PATCH RFC 6.6.y 13/15] null_blk: Remove usage of the deprecated ida_simple_xx() API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 95931a245b44ee04f3359ec432e73614d44d8b38 ]

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.
