Subject: eventfd: Remove usage of the deprecated ida_simple_xx() API
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=434225230081b2b3435703decfa9c4214aac22ce;p=linux.git

eventfd: Remove usage of the deprecated ida_simple_xx() API

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

This is less verbose.
