H A Dbase.cc5141e6d Tue May 08 02:26:15 CDT 2007 Eric Dumazet <dada1@cosmosbay.com> procfs: reorder struct pid_dentry to save space on 64bit archs, and constify them

Change the order of fields of struct pid_entry (file fs/proc/base.c) in order
to avoid a hole on 64bit archs. (8 bytes saved per object)

Also change all pid_entry arrays to be const qualified, to make clear they
must not be modified.

Before (on x86_64) :

# size fs/proc/base.o
text data bss dec hex filename
15549 2192 0 17741 454d fs/proc/base.o

After :

# size fs/proc/base.o
text data bss dec hex filename
17229 176 0 17405 43fd fs/proc/base.o

Thats 336 bytes saved on kernel size on x86_64
