From: K Prateek Nayak Date: Mon, 23 Dec 2024 04:34:00 +0000 (+0000) Subject: x86/itmt: Convert "sysctl_sched_itmt_enabled" to boolean X-Git-Tag: v6.14-rc1~184^2~11 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2f6f726bdda5f24227de10bc599038e0ca0d65f4;p=thirdparty%2Fkernel%2Flinux.git x86/itmt: Convert "sysctl_sched_itmt_enabled" to boolean In preparation to move "sysctl_sched_itmt_enabled" to debugfs, convert the unsigned int to bool since debugfs readily exposes boolean fops primitives (debugfs_read_file_bool, debugfs_write_file_bool) which can streamline the conversion. Since the current ctl_table initializes extra1 and extra2 to SYSCTL_ZERO and SYSCTL_ONE respectively, the value of "sysctl_sched_itmt_enabled" can only be 0 or 1 and this datatype conversion should not cause any functional changes.
