      xfs: event tracing support · 0b1b213f
      Christoph Hellwig 提交于
      Convert the old xfs tracing support that could only be used with the
      out of tree kdb and xfsidbg patches to use the generic event tracer.
      
      To use it make sure CONFIG_EVENT_TRACING is enabled and then enable
      all xfs trace channels by:
      
         echo 1 > /sys/kernel/debug/tracing/events/xfs/enable
      
      or alternatively enable single events by just doing the same in one
      event subdirectory, e.g.
      
         echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable
      
      or set more complex filters, etc. In Documentation/trace/events.txt
      all this is desctribed in more detail.  To reads the events do a
      
         cat /sys/kernel/debug/tracing/trace
      
      Compared to the last posting this patch converts the tracing mostly to
      the one tracepoint per callsite model that other users of the new
      tracing facility also employ.  This allows a very fine-grained control
      of the tracing, a cleaner output of the traces and also enables the
      perf tool to use each tracepoint as a virtual performance counter,
           allowing us to e.g. count how often certain workloads git various
           spots in XFS.  Take a look at
      
          http://lwn.net/Articles/346470/
      
      for some examples.
      
      Also the btree tracing isn't included at all yet, as it will require
      additional core tracing features not in mainline yet, I plan to
      deliver it later.
      
      And the really nice thing about this patch is that it actually removes
      many lines of code while adding this nice functionality:

      xfs: merge fsync and O_SYNC handling · 13e6d5cd
      Christoph Hellwig 提交于
      The guarantees for O_SYNC are exactly the same as the ones we need to
      make for an fsync call (and given that Linux O_SYNC is O_DSYNC the
      equivalent is fdadatasync, but we treat both the same in XFS), except
      with a range data writeout.  Jan Kara has started unifying these two
      path for filesystems using the generic helpers, and I've started to
      look at XFS.
      
      The actual transaction commited by xfs_fsync and xfs_write_sync_logforce
      has a different transaction number, but actually is exactly the same.
      We'll only use the fsync transaction going forward.  One major difference
      is that xfs_write_sync_logforce never issues a cache flush unless we
      commit a transaction causing that as a side-effect, which is an obvious
      bug in the O_SYNC handling.  Second all the locking and i_update_size
      vs i_update_core changes from 978b7237
      never made it to xfs_write_sync_logforce, so we add them back.
      
      To make xfs_fsync easily usable from the O_SYNC path, the filemap_fdatawait
      call is moved up to xfs_file_fsync, so that we don't wait on the whole
      file after we already waited for our portion in xfs_write.
      
      We'll also use a plain call to filemap_write_and_wait_range instead
      of the previous sync_page_rang which did it in two steps including
      an half-hearted inode write out that doesn't help us.
      
      Once we're done with this also remove the now useless i_update_size
      tracking.

      [XFS] Sanitise xfs_log_force error checking. · b911ca04
      David Chinner 提交于
      xfs_log_force() is declared to return an error, but we almost never check
      it. We don't need to check it in most cases; if there's a log I/O error
      then we'll be shutting down the filesystem anyway and that means we'll
      catch the error somewhere else.
      
      However, on certain calls we should be returning an error - sync
      transactions, fsync, sync writes, etc. so this isn't a pure black and
      white distinction. Hence make xfs_log_force() a void function that issues
      a warning to the syslog on error, and call _xfs_log_force() in all the
      places where we actually care about the error status returned.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
