* performance/write-behind: initialize lock in wb-file before wb-file is set ↵v3.0.8qa1v3.0.8Raghavendra G2011-05-071-23/+29
| | | | | | | | | | | | | | | | | | | 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.
