* statedump: do not print the inode number in the statedumpRaghavendra Bhat2011-10-011-58/+28
| | | | | | | | | | | | | 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.Jeff Darcy2011-09-071-3/+0
| | | | | | | | | | | | | | | | 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 ↵branchpoint-3.2Raghavendra G2011-04-291-20/+26
| | | | | | | | | | | | | | | | | | | in fd-ctx. - 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.
