| |
This text refers to the "first 7 functions", which was correct when written but became incorrect when Johannes Weiner added another function to the list in 139e561660fe ("lib: radix_tree: tree node interface").
Remove the sentence because it doesn't add any additional information and would need to be updated each time the list changes.
Signed-off-by: Adam Barth <aurorean@gmail.com> --- Changes in v2: - Removed the sentence entirely, as suggested by derRichard.
