ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_max() is inclusive. So a -1 has been added when needed. Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Reviewed-by: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx> --- This patch has been sent about 5 months ago [1] and has been A-by just a few minutes after. A gentle reminder has been sent 3 months later [2]. However, it has still not reached -next since then in the last 2 months. So, I've added the R-b tag and I'm adding Andrew Morton in To:, in order to help in the merge process.
