udf: refactor inode_bmap() to handle error

2024-10-02T12:32:29+00:00

Refactor inode_bmap() to handle error since udf_next_aext() can return error now. On situations like ftruncate, udf_extend_file() can now detect errors and bail out early without resorting to checking for particular offsets and assuming internal behavior of these functions.

udf: refactor udf_next_aext() to handle error

2024-10-02T12:10:50+00:00

Since udf_current_aext() has error handling, udf_next_aext() should have error handling too. Besides, when too many indirect extents found in one inode, return -EFSCORRUPTED; when reading block failed, return -EIO.

udf: refactor udf_current_aext() to handle error

2024-10-02T10:37:01+00:00

As Jan suggested in links below, refactor udf_current_aext() to differentiate between error, hit EOF and success, it now takes pointer to etype to store the extent type, return 1 when getting etype success, return 0 when hitting EOF and return -errno when err.

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
