Return to handle.h CVS log

Up to [Development] / xfs-cmds / xfsprogs / include

Some of the libhandle routines were not clear whether they were working
on fshandles or file handles.  This mod renames open_by_handle() to
open_by_fshandle() and updates any calling applications to now call
open_by_fshandle() instead.  A new open_by_handle() has been created.

path_to_fshandle() was trying to maintain a hash of fshandles but the
hash was only storing a max of 2 fshandles at a time.  This has been
fixed so the hash can hold multiple fs handles.
define open_by_fshandle()
