is crucial for lib_blkid in identifying the ZFS partition type. To

Drop the no_memory() call from zpool_in_use() when reading the

Furthermore, on Linux it's possible for EREMOTEIO to returned

and not rescanned. In this case we want to fallback to the
legacy scanning method and read any of the labels we can.

This change provides rpm spec macros to sign the zfs and spl kmods as
the final step after the %install scriptlet. This is needed since the
find-debuginfo.sh script strips out debug symbols plus signatures.
Kernel module signing only occurs when the required files are present
as typically required in the Linux source tree:
- certs/signing_key.pem
- certs/signing_key.x509
The method for overriding the default __spec_install_post macro is
inspired by (and largely copied from) the Fedora kernel.spec.

This patch uses existing mechanism to override flush_dcache_page,

it is only used to do some check against HugeTLB pages, which only
