ext4: add more tracepoints and use dev_t in the trace buffer
- Add more ext4 tracepoints. - Change ext4 tracepoints to use dev_t field with MAJOR/MINOR macros so that we can save 4 bytes in the ring buffer on some platforms. - Add sync_mode to ext4_da_writepages, ext4_da_write_pages, and ext4_da_writepages_result tracepoints. Also remove for_reclaim field from ext4_da_writepages since it is usually not very useful. Signed-off-by: Jiaying Zhang <jiayingz@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
