udf: Move udf_adinicb_readpage() to inode.c

2023-01-26T15:46:36Z

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: Switch to single address_space_operations

2023-01-26T15:46:36Z

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()

2023-01-26T15:46:36Z

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
