fs/adfs: add time stamp and file type helpers

2019-06-27T00:14:14+00:00

Add some helpers to check whether the inode has a time stamp and file type, and to parse the file type from the load address. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: clean up indirect disc addresses and fragment IDs

2019-06-27T00:14:14+00:00

We use a variety of different names for the indirect disc address of the current object, use a variety of different types, and print it in a variety of different ways. Bring some consistency to this by naming it "indaddr", use u32 or __u32 as the type since it fits in 32-bits, and always print it with %06x (with no leading hex prefix.) When printing it was a directory identifer, use "dir %06x" otherwise use "object %06x". Do the same for fragment IDs and the parent indirect disc addresses.

fs/adfs: fix filename fixup handling for "/" and "//" names

2019-05-31T09:31:07+00:00

Avoid translating "/" and "//" directory entry names to the special "." and ".." names by instead converting the first character to "^". Acked-by: Al Viro Signed-off-by: Russell King

fs/adfs: move append_filetype_suffix() into adfs_object_fixup()

2019-05-31T09:31:05+00:00

append_filetype_suffix() is now only used in adfs_object_fixup(), so move it there. Acked-by: Al Viro Signed-off-by: Russell King

fs/adfs: remove truncated filename hashing

2019-05-31T09:31:00+00:00

fs/adfs support for truncated filenames is broken, and there is a desire not to support this into the future. Let's remove the fs/adfs support for this. Viro says: "FWIW, the word from Linus had been basically "kill it off" on truncation." That being: "Make it so. Make the rule be that d_hash() can only change the hash itself, rather than the subtle special case for len that we had because of legacy reasons.." Acked-by: Al Viro Signed-off-by: Russell King

fs/adfs: factor out filename fixup

2019-05-31T09:30:57+00:00

Move the filename fixup to adfs_object_fixup() so we only have one implementation of this. Acked-by: Al Viro Signed-off-by: Russell King

fs/adfs: factor out object fixups

2019-05-31T09:30:54+00:00

Factor out the directory object fixups, which parse the filetype and optionally apply the filetype suffix to the filename. Acked-by: Al Viro Signed-off-by: Russell King

fs/adfs: factor out filename case lowering
