As for the Linux 5.18 kernel bio_alloc() expects a block_device struct as an argument. This removes the need for the bio_set_dev() compatibility code for 5.18 and newer kernels. Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes openzfs#13515
Linux 5.19 commit torvalds/linux@70200574cc removed the blk_queue_discard() helper function. The preferred interface is to now use the bdev_max_discard_sectors() function to check for discard support.

Linux 5.19 commit torvalds/linux@44abff2c0 removed the blk_queue_secure_erase() helper function.

Linux 5.19 commit torvalds/linux@44abff2c0 splits the secure erase functionality from the blkdev_issue_discard() function. The blkdev_issue_secure_erase() must now be issued to issue a secure erase.

As of the Linux 5.19 kernel the readpage() address space operation has been replaced by read_folio(). Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes openzfs#13515
As of the Linux 5.19 kernel the disk_*_io_acct() helper functions have been replaced by the bdev_*_io_acct() functions. Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes openzfs#13515
As of the Linux 5.19 kernel an identically named zap_flags_t typedef is declared in the include/linux/mm_types.h linux header. Sadly, the inclusion of this header cannot be easily avoided. To resolve the conflict a #define is used to remap the name in the OpenZFS sources when building against the Linux kernel.

As of the Linux 5.19 kernel the asm/fpu/internal.h header was entirely removed. It has been effectively empty since the 5.16 kernel and provides no required functionality.
