Subject: btrfs: tests: Fix a memory leak in error handling path in 'run_test()'
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9ca2e97fa3c3216200afe35a3b111ec51cc796d2;p=openwrt%2Fstaging%2Fblogic.git

btrfs: tests: Fix a memory leak in error handling path in 'run_test()'

If 'btrfs_alloc_path()' fails, we must free the resources already
allocated, as done in the other error handling paths in this function.
