nilfs2: add tracepoints for analyzing reading and writing metadata files
This patch adds tracepoints for analyzing requests of reading and writing
metadata files. The tracepoints cover every in-place mdt files (cpfile,
sufile, and datfile).
Example of tracing mdt_insert_new_block():
cp-14635 [000] ...1 30598.199309: nilfs2_mdt_insert_new_block: inode = ffff88022a8d0178 ino = 3 block = 155
cp-14635 [000] ...1 30598.199520: nilfs2_mdt_insert_new_block: inode = ffff88022a8d0178 ino = 3 block = 5
cp-14635 [000] ...1 30598.200828: nilfs2_mdt_insert_new_block: inode = ffff88022a8d0178 ino = 3 block = 253
