Subject: [PATCH 10/27] mod: fix module object file lookup
|
|
|
|
On systems where vmlinux file is not under /usr/lib/debug/lib/modules
|
|
directory, 'mod -s|-S' command may fail to find the module's object
|
|
file with the below error:
|
|
|
|
mod: cannot find or load object file for sd_mod module
|
|
|
|
Fix it by trying all possible module object file extentions while
|
|
searching for the object file under /usr/lib/debug/lib/modules
|
|
directory.
