2011-08-11blktrace: add FLUSH/FUA supportNamhyung Kim
Add FLUSH/FUA support to blktrace. As FLUSH precedes WRITE and/or FUA follows WRITE, use the same 'F' flag for both cases and distinguish them by their (relative) position. The end results look like (other flags might be shown also): - WRITE: W - WRITE_FLUSH: FW - WRITE_FUA: WF - WRITE_FLUSH_FUA: FWF Note that we reuse TC_BARRIER due to lack of bit space of act_mask so that the older versions of blktrace tools will report flush requests as barriers from now on.

2011-08-08regmap: Add basic tracepointsMark Brown
Trace single register reads and writes, plus start/stop tracepoints for the actual I/O to see where we're spending time. This makes it easy to have always on logging without overwhelming the logs and also lets us take advantage of all the context and time information that the trace subsystem collects for us. We don't currently trace register values for bulk operations as this would add complexity and overhead parsing the cooked data that's being worked with.

2011-07-09writeback: trace global_dirty_stateWu Fengguang
Add trace event balance_dirty_state for showing the global dirty page counts and thresholds at each global_dirty_limits() invocation. This will cover the callers throttle_vm_writeout(), over_bground_thresh() and each balance_dirty_pages() loop. Signed-off-by: Wu Fengguang <fengguang.wu@intel.com>
2011-07-09writeback: make writeback_control.nr_to_write straightWu Fengguang
Pass struct wb_writeback_work all the way down to writeback_sb_inodes(), and initialize the struct writeback_control there. struct writeback_control is basically designed to control writeback of a single file, but we keep abuse it for writing multiple files in writeback_sb_inodes() and its callers. It immediately clean things up, e.g. suddenly wbc.nr_to_write vs work->nr_pages starts to make sense, and instead of saving and restoring pages_skipped in writeback_sb_inodes it can always start with a clean zero value. It also makes a neat IO pattern change: large dirty files are now written in the full 4MB writeback chunk size, rather than whatever remained quota in wbc->nr_to_write.
