There is the issue of duplicate executable names and data file to be concerned about. It is a name-space problem. It is not unique to this case, example /usr/bin. This problem is better solved without adding the complexity of hierarchical directory structure. 1. Individual test Makefiles ensure unique names for their executables and data files. This can be done as a process when new tests are accepted. 2. Install process makes sure they are unique - this patch is solving the problem by creating a directory hierarchy. A simpler way to do it is by adding pre-fix to when there is name space conflict. The problem with directory hierarchy is for one thing: 1. It is complex and way too many directories get created during install and this problem will mushroom as more and more tests get added. 2. User won't be able to define a simple path variable to invoke individual tests. This is a user experience problem. Please find a way to solve the name-space problem without the complexity of directory hierarchy. thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Open Source Innovation Group Samsung Research America (Silicon Valley) shuahkh@xxxxxxxxxxxxxxx | (970) 217-8978 -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
