orangefs: clean up debugfs globals

2016-08-15T15:38:36+00:00

Mostly this is moving code into orangefs-debugfs.c so that globals turn
into static globals.

Then gossip_debug_mask is renamed orangefs_gossip_debug_mask but keeps
global visibility, so it can be used from a macro.

orangefs: Cache getattr results.

2016-08-02T19:38:45+00:00

The userspace component attempts to do this, but this will prevent
us from even needing to go into userspace to satisfy certain getattr
requests.

orangefs: Add KERN_ to gossip_ macros

2016-04-08T18:10:45+00:00

Emit the logging messages at the appropriate levels.

Miscellanea:

o Change format to fmt
o Use the more common ##__VA_ARGS__

Orangefs: optimize boilerplate code.

2016-04-08T18:08:27+00:00

Suggested by David Binderman 
The former can potentially be a performance win over the latter.

memcpy(d, s, len);
memset(d+len, c, size-len);

memset(d, c, size);
memcpy(d, s, len);

orangefs: Implement inode_operations->permission().

2016-02-04T19:12:37+00:00

Thus d_revalidate is not obliged to check on as much, which will
eventually lead the way to hammering the filesystem servers much less.

Orangefs: change pvfs2 filenames to orangefs

2015-12-04T17:56:14+00:00

Also changed references within source files that referred to
header files whose names had changed.

OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.

2015-12-03T19:45:44+00:00

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.
