/* Compute d_ino by combining filename hash with directory hash. */
* smallprint.cc (__small_vswprintf): Fix uninitialized usage of `w'. Revamp advisory file locking to avoid cross reference pointers as well as to allow BSD flock semantics. More agressively delete unused nodes and sync objects. * fhandler.h (fhandler_base::ino): Rename from namehash. Fix comment. (fhandler_base::node): Remove. (fhandler_base::unique_id): Add. (fhandler_base::del_my_locks): New method. (get_ino): Rename from get_namehash. Change usage throughout Cygwin.

Use NtQueryInformationFile(FileStandardInformation) instead of calling fstat_by_handle. Always unlock node before returning. Use fhandler's unique id to create lf_id for BSD flock locks. Rely on node lock from inode_t::get. Call del_lock_obj on removed locks here to allow explicit unlocking. Delete node if no lock exists on the file anymore. (lf_setlock): Get file handle as additional parameter. Handle the fact that lf_getblock now always opens the attached event object.
