/* 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.

(fhandler_base::open_fs): Fill ino with inode number if FS has good inodes. Allocate a LUID and store in unique_id to recognize file descriptors referencing the same file object. * flock.cc: Drop flock TODO comments. Use explicit types __dev32_t and __ino64_t instead of dev_t and ino_t. (LOCK_OBJ_NAME_LEN): Change to reflect longer lf_id length. (get_obj_handle_count): New method.

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. Reactivate erroneously applied patch which deactivates setting thread priority. Additionally handle blocking on BSD flock locks. (lf_clearlock): Get file handle as additional parameter. (lf_getlock): Close event handle opened by lf_getblock. (lf_getblock): Open potentially blocking event object here and check its signal state if it's a BSD flock lock.
