lttng-modules: Fix do_compile failure for btrfs related tracepoints
Building lttng-modules with linux-yocto-dev will cause do_compile failure: lttng-modules/2.10.6-r0/lttng-modules-2.10.6/probes/../probes/lttng-tracepoint-event-impl.h:143:6: error: conflicting types for 'trace_btrfs_reserve_extent' void trace_##_name(_proto); ^~~~~~ The following commit from latest mainline kernel changes some btrfs functions' prototype. 3dca5c942dac60164e6a6e89172f25b86af07ce7 "btrfs: trace: Remove unnecessary fs_info parameter for btrfs__reserve_extent event class" This patch backports a commit from upstream to meet the above changes. 51ab0b1da29354375a19f865abcd233dd2178295 "Fix: btrfs: Remove unnecessary fs_info parameter" (From OE-Core rev: c1daa5c0b89cdfab15d2fa093b021b2ce0937dad) Signed-off-by: He Zhe <zhe.he@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

12 btrfs: trace: Remove unnecessary fs_info parameter for btrfs__reserve_extent event class
13
14 fs_info can be extracted from btrfs_block_group_cache, and all
15 btrfs_block_group_cache is created by btrfs_create_block_group_cache()
16 with fs_info initialized, no need to worry about NULL pointer
17 dereference.
