Peter Anvin" Date: Tue, 24 Jun 2014 11:26:18 -0700 Subject: [PATCH] x86/vdso: Make vdso2c print the number of sections needed on error If we run out of space for section, at least make the error message print the amount of space we need so we can actually diagnose it. Furthermore, the test should be > instead of >= (it is okay to have exactly the maximum number of sections.) Signed-off-by: H.
