udf: Move udf_adinicb_readpage() to inode.c

2023-01-26T15:46:36+00:00

udf_adinicb_readpage() is only called from aops functions, move it to the same file as its callers and also drop the stale comment - invalidate_lock is protecting us against races with truncate. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara

udf: Mark aops implementation static

2023-01-26T15:46:36+00:00

Mark functions implementing aops static since they are not needed outside of inode.c anymore. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara

udf: Switch to single address_space_operations

2023-01-26T15:46:36+00:00

Now that udf_aops and udf_adiniicb_aops are functionally identical, just drop udf_adiniicb_aops. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara

udf: Convert all file types to use udf_write_end()

2023-01-26T15:46:36+00:00

Switching address_space_operations while a file is used is difficult to do in a race-free way. To be able to use single address_space_operations in UDF, create udf_write_end() function that is able to handle both normal and in-ICB files. Reviewed-by: Christoph Hellwig Signed-off-by: Jan Kara

udf: Allocate blocks on write page fault

2023-01-26T15:46:35+00:00

Currently if file with holes is mapped, udf allocates blocks for dirtied pages during page writeback. This however creates problems when to truncate final extent to proper size and currently we leave the last extent untruncated which violates UDF standard. So allocate blocks on write page fault instead. In that case the last extent gets truncated the file is closed and everything is happy. Signed-off-by: Jan Kara

udf: Fold udf_block_map() into udf_map_block()
