Many tracepoints were populating an ext4_allocation_context to pass in, but this requires a slab allocation even when tracepoints are off. In fact, 4 of 5 of these allocations were only for tracing. In addition, we were only using a small fraction of the 144 bytes of this structure for this purpose. We can do away with all these alloc/frees of the ac and simply pass in the bits we care about, instead. I tested this by turning on tracing and running through xfstests on x86_64. I did not actually do anything with the trace output, however. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> |
