2016-10-07vfs: Remove {get,set,remove}xattr inode operationsAndreas Gruenbacher1-3/+0
These inode operations are no longer used; remove them. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2016-09-27fs: Replace current_fs_time() with current_time()Deepa Dinamani1-5/+5
current_fs_time() uses struct super_block* as an argument. As per Linus's suggestion, this is changed to take struct inode* as a parameter instead. This is because the function is primarily meant for vfs inode timestamps. Also the function was renamed as per Arnd's suggestion. Change all calls to current_fs_time() to use the new current_time() function instead. current_fs_time() will be deleted.

2016-09-27fs: make remaining filesystems use .rename2Miklos Szeredi1-2/+6
This is trivial to do: - add flags argument to foo_rename() - check if flags is zero - assign foo_rename() to .rename2 instead of .rename This doesn't mean it's impossible to support RENAME_NOREPLACE for these filesystems, but it is not trivial, like for local filesystems. RENAME_NOREPLACE must guarantee atomicity (i.e. it shouldn't be possible for a file to be created on one host while it is overwritten by rename on another host). Filesystems converted: 9p, afs, ceph, coda, ecryptfs, kernfs, lustre, ncpfs, nfs, ocfs2, orangefs. After this, we can get rid of the duplicate interfaces for rename.

2016-08-16orangefs: rename most remaining global variablesMartin Brandenburg1-4/+4
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>

The userspace component attempts to do this, but this will prevent us from even needing to go into userspace to satisfy certain getattr requests. Signed-off-by: Martin Brandenburg <martin@omnibond.com>

2016-03-09orangefs: Avoid symlink upcall if target is too long.Martin Brandenburg1-0/+3
Previously the client-core detected this condition by sheer luck! Since we used strncpy, no NUL byte would be included on the name. The client-core would call strlen, which would read past the end of its buffer, but return a number large enough that the client-core would return ENAMETOOLONG.

2015-12-03OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.Yi Liu1-67/+67
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.
