Subject: [PATCH 464/465] storage/posix: Remove nr_files usage
14f8ab
14f8ab
nr_files is supposed to represent the number of files opened in posix.
14f8ab
Present logic doesn't seem to handle anon-fds because of which the
14f8ab
counts would always be wrong.
14f8ab
14f8ab
I don't remember anyone using this value in debugging any problem probably
14f8ab
because we always have 'ls -l /proc/<pid>/fd' which not only prints the
14f8ab
fds that are active but also prints their paths. It also handles directories
14f8ab
and anon-fds which actually opened the file. So removing this code
14f8ab
instead of fixing the buggy logic to have the nr_files.
