Hi all, Here's a first version of sysfs support for XFS. This is based on and incorporates feedback from the rfc, available here: http://oss.sgi.com/archives/xfs/2014-05/msg00425.html The idea of using debugfs instead was brought up, but not much discussion around it, so I've left things as is with respect to using sysfs. This series creates new xfs_sysfs.[c,h] source files to contain the general infrastructure for sysfs attribute files in XFS, creates a global kset for the module (represented as /sys/fs/xfs) and embeds a couple kobjects to start creating an attribute heirarchy. Patch 1 fixes what looks like a couple minor error handling errors in xfs_mountfs(). Patches 2-5 add the sysfs infrastructure, objects and attributes. Patch 6 adds documentation for the newly defined attributes. Thoughts, reviews, flames appreciated. Brian v1: - Move sysfs infrastructure code to new source file, add helpers for object initialization, etc. - Created an xfs_mount->xlog object heirarchy for attributes associated with the log. - Renamed the reserve/write grant head attributes to '[reserve,write]_grant_head.' - Use the 'cycle:block' or 'cycle:bytes' decimal format for attributes (rather than export encoded values). - Included generic mountfs fix and doc. Brian Foster (6): xfs: fix a couple error sequence jumps in xfs_mountfs() xfs: add a sysfs kset xfs: add xfs_mount sysfs kobject xfs: add xlog sysfs kobject and attribute handlers xfs: add log attributes for log lsn and grant head data xfs: document log sysfs attributes in testing ABI Documentation/ABI/testing/sysfs-fs-xfs | 39 ++++++++ fs/xfs/Makefile | 1 + fs/xfs/xfs_log.c | 9 ++ fs/xfs/xfs_log_priv.h | 3 + fs/xfs/xfs_mount.c | 19 +++- fs/xfs/xfs_mount.h | 2 + fs/xfs/xfs_super.c | 12 ++- fs/xfs/xfs_sysfs.c | 175 +++++++++++++++++++++++++++++++++ fs/xfs/xfs_sysfs.h | 47 +++++++++ 9 files changed, 303 insertions(+), 4 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-fs-xfs create mode 100644 fs/xfs/xfs_sysfs.c create mode 100644 fs/xfs/xfs_sysfs.h -- 1.8.3.1 _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
