Subject: ksmbd: Remove usage of the deprecated ida_simple_xx() API
X-Git-Tag: v6.8-rc1~113^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ebfee7ad2722f84064d241b5319a7085b881b584;p=thirdparty%2Fkernel%2Flinux.git

ksmbd: 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.

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So change a 0xFFFFFFFF into a 0xFFFFFFFE in
order to keep the same behavior.
