However, the latter is more used within the kernel. In order to remove strtobool() and slightly simplify kstrtox.h, switch to the other function name. While at it, include the corresponding header file () Signed-off-by: Christophe JAILLET Reviewed-by: Zenghui Yu --- This patch was already sent as a part of a serie ([1]) that axed all usages of strtobool(). Most of the patches have been merged in -next. I synch'ed with latest -next and re-send the remaining ones as individual patches.
