"This patch series also introduces a new small shell script wrapper, called scripts/checkfiles, that checks the compliance of source files (not in diff format); the script can operate on any mix of files and directories (recursively checking)," Erez Zadok stated describing a patch posted to the Linux Kernel mailing list. The small script works by recursively walking through a specified directory, running checkpatch on a diff of each source file against /dev/null. Erez added, "I ran the above script and it found nearly 1.5 million reported warnings/errors, with drivers being the largest abuser, not surprisingly." He then offered a breakdown of the warnings within each top level directory, summarizing, "1,464,313 total, any volunteers? :-)"
