ext4: Support for checksumming from journal triggers

ext4_journal_get_write_access() now has 4 arguments, provide
a compat wrapper for older kernels.

Linux: v5.11-rc5-9-g309dca309fc3

created bio_set_dev macro
Linux: v5.15-rc6-127-gcf6d6238cdd3

created inline function(s).

Provide a bio_set_dev implementation if one is not provided
by the kernel.

Linux v5.12-rc1-20-ga8affc03a9b3
block: rename BIO_MAX_PAGES to BIO_MAX_VECS

Provide a fallback for older kernels when BIO_MAX_VECS is
not defined

sched: Change task_struct::state
v5.13-rc6-64-gd6c23bb3a2ad

Provide a get_current_state() replacement for older kernels
where it is not available.

EXT4_DIR_REC_LEN and EXT4_DIR_ENTRY_LEN requires inode parent dir's
inode.

ext4fs_dirhash requires inode parent dir's inode, use a wrapper
for older kernels.
