debugfs.c: the max length of debugfs argument is too short
|
|
|
|
The max length of debugfs argument is 256 which is too short, the
|
|
arguments are two paths, the PATH_MAX is 4096 according to
|
|
/usr/include/linux/limits.h, so use BUFSIZ (which is 8192 on Linux
|
|
systems), that's also what the ss library uses.
