f698a9998c ceph: validate snapdirname option length when mounting
commit 12eb22a5a609421b380c3c6ca887474fb2089b2c upstream.

It becomes a path component, so it shouldn't exceed NAME_MAX
characters.  This was hardened in commit c152737be22b ("ceph: Use
strscpy() instead of strcpy() in __get_snap_name()"), but no actual
check was put in place.

4765afab38 ceph: fix incorrect kmalloc size of pagevec mempool
[ Upstream commit 03230edb0bd831662a7c08b6fef66b2a9a817774 ]

The kmalloc size of pagevec mempool is incorrectly calculated.
It misses the size of page pointer and only accounts the number for the array.

Fixes: a0102bda5bc0 ("ceph: move sb->wb_pagevec_pool to be a global mempool")
