isofs: Use -y instead of -objs in Makefile

2024-05-09T16:09:57+00:00

*-objs suffix is reserved rather for (user-space) host programs while
usually *-y suffix is used for kernel drivers (although *-objs works
for that purpose for now).

Let's correct the old usages of *-objs in Makefiles.

isofs: Remove calls to set/clear the error flag

2024-04-23T21:22:11+00:00

Nobody checks the error flag on isofs folios, so stop setting and
clearing it.

This also renames iso9660_options to isofs_options, for

isofs: remove SLAB_MEM_SPREAD flag usage

2024-03-05T14:15:43+00:00

The SLAB_MEM_SPREAD flag is already a no-op after removal of SLAB
allocator and in [1] it was fully deprecated. Remove its usage so we can
delete it from slab. No functional change.

isofs: handle CDs with bad root inode but good Joliet root directory

2024-02-08T10:59:37+00:00

I have a CD copy of the original Tom Clancy's Ghost Recon game from
2001. The disc mounts without error on Windows, but on Linux mounting
fails with the message "isofs_fill_super: get root inode failed". The
error originates in isofs_read_inode, which returns -EIO because de_len
is 0. The superblock on this disc appears to be intentionally corrupt as
a form of copy protection.

When the root inode is unusable, instead of giving up immediately, try
to continue with the Joliet file table. This fixes the Ghost Recon CD
and probably other copy-protected CDs too.

fs: add CONFIG_BUFFER_HEAD

2023-08-02T15:13:09+00:00

Add a new config option that controls building the buffer_head code, and
select it from all file systems and stacking drivers that need it.

For the block device nodes and alternative iomap based buffered I/O path
is provided when buffer_head support is not enabled, and iomap needs a
a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call
into the buffer_head code when it doesn't exist.

Otherwise this is just Kconfig and ifdef changes.
