Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/miscfs/procfs: procfs.h procfs_vfsops.c procfs_vnops.c

Log Message:
If the calling process is running under linux emulation, make /proc/xxx/fd/
return only symlinks pointing to the original file in the filesystem,
instead of a hard link. This matches the linux behavior, and some
linux programs relies on it (they unconditionally call readlink() on
/proc/xxx/fd/yy and don't deal with it returning EINVAL).
