Hello- Following is the next iteration of the series to add xfs stats to sysfs. This iteration adds patch 5/5 to incorporate sysfs/kobject into xfsstats. ----------history--------------- v7: -add patch 5/5: incorporate sysfs/kobject in xfsstats: handlers take kobjects. Allocate & deallocate per-fs stats structures and set up the sysfs entries for them. Add kobject and a pointer to a per-cpu struct xfsstats. Modify the macros that manipulate the stats accordingly. v6: -add patch 4/4: move to_xlog(kobject) to the relevant show/store operations. This keeps the xfs_sysfs_object_show/store functions generic. Also, with the change, there can be some cleanup of the show/store function arguments. v5: -optimization of sysfs_ops function. -style fixups v4: -whitespace fixup of patch 1 -add patch 4 (sysfs ops consolidation - dbg, stats, log) v3: -style fixups and removal of extraneous printk. v2: -style fixups. v1: -------------------------------- The series provides 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. Patch 4 consolidates the sysfs ops for dbg, stats, log. Patch 5 allocates and deallocates per-fs stats structures and sets up the sysfs entries for them. Add kobject and a pointer to a per-cpu struct xfsstats. Modify the macros that manipulate the stats accordingly. Again, comments and questions are welcome.
