Hello everyone,
Please forgive my delayed reply.
Consider the following scenario:
1. Mount YAFFS2.
2. Create symbolic link.
yaffs_CloneString( ) gets called and memory is allocated.
3. Unmount YAFFS2.
yaffs_DestroyObject( ) is not called.
yaffs)_UnlinkWorker( ) is also not called.
I am not sure, maybe we should free the memory in yaffs_DeinitialiseObjects( ).
Thanks,
Rohit
