When a linux app calls mkdir if the call has a trailing / then
it can fail unexpectedly e.g
1. mkdir( '/root/.test', 511 )
2. mkdir( '/root/.test/test2/', 511 )
If the above is run in sequence #1 succeeds yet #2 fails.
The reason is #1 is operating in compat space where as
#2 reverts to operating in standard space.
Changing #2 to:
mkdir( '/root/.test/test2', 511 )
Ensures the correct behaviour but obviously #2 should work
correctly without change.
A change to linux_file.c -> linux_mkdir to ensure no trailing
/ exists before calling LCONVPATHCREAT fixes the issue but
I believe the actual error is in vfs_lookup.c =>
kern_alternate_path
