statedump: do not print the inode number in the statedump

2011-10-01T12:55:22+00:00

    Since gfid is used to uniquely identify a inode, in the statedump
    printing inode number is not necessary. Its suffecient if the gfid
    of the inode is printed. And do not print the the inodelks, entrylks
    and posixlks if the lock count is 0.

Eliminate many "var set but not used" warnings with newer gcc.

2011-09-08T06:48:01+00:00

This fixes ~200 such warnings, but leaves three categories untouched.

(1) Rpcgen code.

(2) Macros which set variables in the outer (calling function) scope.

(3) Variables which are set via function calls which may have side effects.

performance/write-behind: initialize lock in wb-file before wb-file is set in fd-ctx.

2011-04-29T13:59:41+00:00

- Consider a combination of fuse->quick-read->read-ahead->wb->client.
    quick-read can do open-behind (open is returned as success even
    before it is issued to backend) and hence the fd can already be
    in the list of open fds of the inode. A flush call on some other
    fd opened on the same inode, will result in ra_flush issuing flush
    calls to all the fds opened on the same inode. This can result in
    wb_flush trying to hold a lock on non-initialized lock there by causing
    memory corruption.
