This series adds an initial set of tracepoints for ntfs3 core paths.
The tracepoints cover:
- mount and log replay
- namei operations
- directory index operations
- allocation and block mapping
- iomap operations
- file I/O entry points
Changes in v4 (both addressing review comments on patch 5):
- ntfs3_attr_data_get_block: pass the "new" pointer to the trace
event directly and move the "new != NULL" check into
TP_fast_assign(), keeping that logic out of the call site and only
executed when the event is enabled
- ntfs3_attr_set_size_ex: stop sampling the old size with
i_size_read() in TP_fast_assign() - on the truncate path
truncate_setsize() has already updated i_size to the new value, so
the recorded old_size always equaled new_size. Read the actual old
size from the on-disk attribute record and pass it as an explicit
parameter; move the call site after the attribute lookup so both
resident and non-resident attributes are covered
