Dominique Martinet 22e424feb6 Revert "fs/9p: search open fids first" ... This reverts commit 478ba09edc. That commit was meant as a fix for setattrs with by fd (e.g. ftruncate) to use an open fid instead of the first fid it found on lookup. The proper fix for that is to use the fid associated with the open file struct, available in iattr->ia_file for such operations, and was actually done just before in 6624664160 ("9p: retrieve fid from file when file instance exist.") As such, this commit is no longer required. Furthermore, changing lookup to return open fids first had unwanted side effects, as it turns out the protocol forbids the use of open fids for further walks (e.g. clone_fid) and we broke mounts for some servers enforcing this rule. Note this only reverts to the old working behaviour, but it's still possible for lookup to return open fids if dentry->d_fsdata is not set, so more work is needed to make sure we respect this rule in the future, for example by adding a flag to the lookup functions to only match certain fid open modes depending on caller requirements.
