(Minor whitespace and braces fixups.) As a part of that, the /proc/fs/xfs/stat file becomes a symlink to the sysfs stats entry. The series provides the beginnings of the infrastructure for per-fs stats (in addition to global accumulative stats). We already have per-fs information in /sys, so it makes sense to have per-fs stats there too. As a first step, moving existing global stats infrastructure to /sys will allow us to re-use that sysfs code for per-fs stats as well. Patch 1 handles the bring-up and tear down of xfs/stats directory structure in sysfs when an fs is mounted. The directory contains the stats file and the stats_clear file. The stats file contents mimic those of /proc/fs/xfs/stat. The stats_clear file is empty, and much like the current stat_clear command, handles the zeroing of the stats file when a "1" is echoed to the stats_clear file. Patch 2 creates the symlink for stats from procfs to sysfs. Patch 3 removes the now unused portions of procfs for stat. Once again, comments and questions are welcome. Thanks- Bill _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
