ext4: avoid clearing beyond i_blocks when truncating an inline data file
ext4: ext4_inode_is_fast_symlink should use EXT4_CLUSTER_SIZE
ext4: fix a typo in extents.c
ext4: use %pd printk specificer
ext4: standardize error handling in ext4_da_write_inline_data_begin()
ext4: retry allocation when inline->extent conversion failed
ext4: enable punch hole for bigalloc
