  ceph: allocate sparse_ext map only for sparse reads (2024-12-16 23:25:44 +0100)

----------------------------------------------------------------
A handful of important CephFS fixes from Max, Alex and myself: memory
corruption due to a buffer overrun, potential infinite loop and several
memory leaks on the error paths.  All but one marked for stable.

----------------------------------------------------------------
Alex Markuze (1):
      ceph: improve error handling and short/overflow-read logic in __ceph_sync_read()

Ilya Dryomov (3):
      ceph: validate snapdirname option length when mounting
      ceph: fix memory leak in ceph_direct_read_write()
      ceph: allocate sparse_ext map only for sparse reads

Max Kellermann (2):
      ceph: fix memory leaks in __ceph_sync_read()
      ceph: give up on paths longer than PATH_MAX
