From ff9da691c0498ff81fdd014e7a0731dab2337dac Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 3 Jun 2010 14:54:39 +0200 Subject: pipe: change /proc/sys/fs/pipe-max-pages to byte sized interface This changes the interface to be based on bytes instead. The API matches that of F_SETPIPE_SZ in that it rounds up the passed in size so that the resulting page array is a power-of-2 in size. The proc file is renamed to /proc/sys/fs/pipe-max-size to reflect this change.
