| H A D | writeback.h | 9fb0a7da Fri Jan 11 15:06:37 CST 2013 Tejun Heo <tj@kernel.org> writeback: add more tracepoints
Add tracepoints for page dirtying, writeback_single_inode start, inode
dirtying and writeback. For the latter two inode events, a pair of
events are defined to denote start and end of the operations (the
starting one has _start suffix and the one w/o suffix happens after
the operation is complete). These inode ops are FS specific and can
be non-trivial and having enclosing tracepoints is useful for external
tracers.
This is part of tracepoint additions to improve visiblity into
dirtying / writeback operations for io tracer and userland.
v2: writeback_dirty_inode[_start] TPs may be called for files on
pseudo FSes w/ unregistered bdi. Check whether bdi->dev is %NULL
before dereferencing.
v3: buffer dirtying moved to a block TP.
