-Subject: [PATCH] dax: Fix compilation for CONFIG_DAX && !CONFIG_FS_DAX
-
-dax_supported() is defined whenever CONFIG_DAX is enabled. So dummy
-implementation should be defined only in !CONFIG_DAX case, not in
-!CONFIG_FS_DAX case.

-Subject: [PATCH] tracing: Make the space reserved for the pid wider
-
-For 64bit CONFIG_BASE_SMALL=0 systems PID_MAX_LIMIT is set by default to
-4194304. During boot the kernel sets a new value based on number of CPUs
-but no lower than 32768. It is 1024 per CPU so with 128 CPUs the default
-becomes 131072 which needs six digits.
-This value can be increased during run time but must not exceed the
-initial upper limit.
-
-Systemd sometime after v241 sets it to the upper limit during boot. The
-result is that when the pid exceeds five digits, the trace output is a
-little hard to read because it is no longer properly padded (same like
-on big iron with 98+ CPUs).
-
-Increase the pid padding to seven digits.
-
