Subject: [PATCH] multipath-tools: mpath-tools.supp: file with valgrind
|
|
suppressions
|
|
|
|
These leaks are caused by other libraries (libsystemd, glibc,
|
|
libgcrypt) and should be ignored when debugging with valgrind
|
|
|
|
Usage example:
|
|
|
|
valgrind --suppressions=mpath-tools.supp \
|
|
--leak-check=full --show-leak-kinds=all $COMMAND
|
