Revert "performance/write-behind: Changed default value of option disable-till to 0"

2009-12-06T21:51:03+00:00

This reverts commit e6c35f74ff4a204cf016ebf201a2630b331f9434.

This commit is found to trigger spurious self heal by causing flush and writev to get
reordered. Reverting as a workaround.

performance/write-behind: fix to bug in setattr which was causing frames to be missed.

2009-10-20T17:18:05+00:00

- local->file was being assigned even before file pointer was got from any of
    the fds opened on the inode, thus making local->file to be NULL. In
    wb_setattr_cbk, since local->file is NULL (and hence file passed to
    wb_process_queue), wb_process_queue does not resume the pending operations
    queued for the file.

2. otherwise check for inode and continue.

performance/write-behind:STACK_UNWIND happens only in failure path of wb_stat()

2009-10-15T16:03:32+00:00

Only in case of errors STACK_UNWIND happens in wb_stat().
Also, fixed an incorrect check which would fail all writes.
