From: Francis Deslauriers Date: Tue, 27 Apr 2021 16:13:57 +0000 (-0400) Subject: Sync lttng-modules ABI in internal kernel-ioctl.h X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=b8e2fb80c105c5a8241f7b35744e4a86d7e4125c;p=lttng-tools.git Sync lttng-modules ABI in internal kernel-ioctl.h This commit bumps the modules minor version number in `kernel-ioctl.h` and applies the following renames: define renames: `LTTNG_KERNEL_x` -> `LTTNG_KERNEL_ABI_x` `RING_BUFFER_x` -> `LTTNG_KERNEL_ABI_RING_BUFFER_x` struct renames: `struct lttng_kernel_x` -> `struct lttng_kernel_abi_x` No behavior change intended.
