Subject: [GIT PULL] vfs pagesize

Hey Linus,

/* Summary */

This enables block sizes greater than the page size for block devices.
With this we can start supporting block devices with logical block sizes
larger than 4k. It also allows to lift the device cache sector size
support to 64k. This allows filesystems which can use larger sector
sizes up to 64k to ensure that the filesystem will not generate writes
that are smaller than the specified sector size.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

No build failures or warnings were observed.

/* Conflicts */
