Merge tag 'vfs-6.15-rc1.pipe' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs pipe updates from Christian Brauner:

 - Introduce struct file_operations pipeanon_fops

 - Don't update {a,c,m}time for anonymous pipes to avoid the performance
   costs associated with it

 - Change pipe_write() to never add a zero-sized buffer

 - Limit the slots in pipe_resize_ring()

 - Use pipe_buf() to retrieve the pipe buffer everywhere

 - Drop an always true check in anon_pipe_write()

 - Cache 2 pages instead of 1

 - Avoid spurious calls to prepare_to_wait_event() in ___wait_event()
