2016-10-24orangefs: don't use d_timeMiklos Szeredi1-2/+3
Instead use d_fsdata which is the same size. Hoping to get rid of d_time, which is used by very few filesystems by this time. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Reviewed-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-08-16orangefs: rename most remaining global variablesMartin Brandenburg1-1/+1
Only op_timeout_secs, slot_timeout_secs, and hash_table_size are left because they are exposed as module parameters. All other global variables have the orangefs_ prefix. Signed-off-by: Martin Brandenburg <martin@omnibond.com>

2016-03-24orangefs: rename orangefs_inode_getattr to orangefs_inode_old_getattrMartin Brandenburg1-1/+1
This is motivated by orangefs_inode_old_getattr's habit of writing over live inodes. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>

2016-02-04orangefs: Implement inode_operations->permission().Martin Brandenburg1-1/+2
Thus d_revalidate is not obliged to check on as much, which will eventually lead the way to hammering the filesystem servers much less. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-01-28orangefs: Fix revalidate.Martin Brandenburg1-37/+61
Previously, it would update a live inode. This was fixed, but it did not ever check that the inode attributes in the dcache are correct. This checks all inode attributes and rejects any that are not correct, which causes a lookup and thus a new getattr. Perhaps inode_operations->permission should replace or augment some of this. There is no actual caching, and this does a rather excessive amount of network operations back to the filesystem server.

2015-12-04Orangefs: change pvfs2 filenames to orangefsMike Marshall1-1/+1
Also changed references within source files that referred to header files whose names had changed. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-12-03OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.Yi Liu1-12/+12
OrangeFS was formerly known as PVFS2 and retains the name in many places. I leave the device /dev/pvfs2-req since this affects userspace. I leave the filesystem type pvfs2 since this affects userspace. Further the OrangeFS sysint library reads fstab for an entry of type pvfs2 independently of kernel mounts. I leave extended attribute keys user.pvfs2 and system.pvfs2 as the sysint library understands these. I leave references to userspace binaries still named pvfs2. I leave the filenames.
