Hitoshi Mitake a9cd207c23 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 Signed-off-by: Hitoshi Mitake <mitake.hitoshi@lab.ntt.co.jp> Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: TK Kato <TK.Kato@wdc.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2015-11-06 17:50:42 -08:00
