NAME=FETCHARG : Set NAME as the argument name of FETCHARG.
FETCHARG:TYPE : Set TYPE as the type of FETCHARG. Currently, basic types
(u8/u16/u32/u64/s8/s16/s32/s64), hexadecimal types
- (x8/x16/x32/x64), "char", "string", "ustring", "symbol", "symstr"
- and bitfield are supported.
+ (x8/x16/x32/x64), VFS layer common type(%pd/%pD), "char",
+ "string", "ustring", "symbol", "symstr" and bitfield are
+ supported.
(\*1) only for the probe on function entry (offs == 0). Note, this argument access
is best effort, because depending on the argument type, it may be passed on
symbols, and you don't need to solve symbol name by yourself.
For $comm, the default type is "string"; any other type is invalid.
+VFS layer common type(%pd/%pD) is a special type, which fetches dentry's or
+file's name from struct dentry's address or struct file's address.
