ext4: Combine proc file handling into a single set of functions
Previously mballoc created a separate set of functions for each proc file. This combines the tunables into a single set of functions which gets used for all of the per-superblock proc files, saving approximately 2k of compiled object code. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
