-----------
xrootdfs: implement xrootdfs_create
Motivation:
In general, a create operation is nice to have.
Especially useful for a dcache xrootd door.
When FUSE has to use mknod, it results in an empty file being created, closed, then opened again for writing.
In dcache this does not work and needs an explicit check to allow overwriting the empty file.
Just appending to the empty file is not possible in dcache, and FUSE does not set the DELETE flag, as it does not expect it to be needed to append to an empty file.
Implementing a create operation makes copying onto dcache faster, as it does not require creating the file twice.
Change:
Implement xrootdfs_create that works as xrootdfs_mknod, except:
- it opens the file over a numbered link, instead of unnumbered, using the same link numbering process as xrootdfs_open
- it creates the wcache for the file
- it does not close the file, and returns the file descriptor
Result:
Copying files on xrootdfs uses the new CREATE function.
The current release of dcache (without the workaround) can be mounted over xrootdfs and used.
