* sysdeps/unix/sysv/linux/fpathconf.c (LINUX_LINK_MAX): Move macro ... * sysdeps/unix/sysv/linux/linux_fsinfo.h (LINUX_LINK_MAX): ... here. * sysdeps/unix/sysv/linux/pathconf.h: New file. (statfs_link_max): New function, guts from fpathconf.c. * sysdeps/unix/sysv/linux/fpathconf.c: Rewritten using that. * sysdeps/unix/sysv/linux/pathconf.c (__pathconf): Likewise. * sysdeps/unix/sysv/linux/alpha/pathconf.c (__pathconf): Rewritten to use the linux/pathconf.c code by #include rather than duplication. * sysdeps/unix/sysv/linux/alpha/fpathconf.c (__pathconf): Likewise.
