What's buInputt? But?


Yes, sorry. It is "but".

Let me know if I should send a v2, or if it can be fixed when it is applied.

ida_alloc_max() is inclusive. So a -1 has been added when needed.

[PATCH] vhost-vdpa: Remove usage of the deprecated ida_simple_xx() API

2024-01-15 Thread Christophe JAILLET
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, buInputt the one of
ida_alloc_max() is inclusive. So a -1 has been added when needed.
