ext4: add flag to ext4_has_free_blocks
This patch adds an allocation request flag to the ext4_has_free_blocks function which enables the use of reserved blocks. This will allow a punch hole to proceed even if the disk is full. Punching a hole may require additional blocks to first split the extents. Because ext4_has_free_blocks is a low level function, the flag needs to be passed down through several functions listed below: ext4_ext_insert_extent ext4_ext_create_new_leaf ext4_ext_grow_indepth ext4_ext_split ext4_ext_new_meta_block ext4_mb_new_blocks ext4_claim_free_blocks ext4_has_free_blocks [ext4 punch hole patch series 1/5 v7] Signed-off-by: Allison Henderson <achender@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Reviewed-by: Mingming Cao <cmm@us.ibm.com>
