Remove all the open coded magic on slot->file_ptr by introducing two helpers that return the file pointer and the flags instead. Signed-off-by:

Two of the three callers want them, so return the more usual format, and shift into the FFS_ form only for the fixed file table. Signed-off-by:

We test file_table.bitmap in io_file_get_fixed() to check invariants, don't do it, it's expensive and was showing up in profiles. No reports of this triggering has come in. Move the check to the file clear instead, which will still catch any wrong usage. Signed-off-by:

THe lifetime of SCM'ed files is bound to ring_sock, which is destroyed strictly after we're done with registered file tables. This means there is no need for the FFS_SCM hack, which was not available on 32-bit builds anyway. Signed-off-by:

From recently io_uring provides an option to allocate a file index for operation registering fixed files. However, it's utterly unusable with mixed approaches when for a part of files the userspace knows better where to place it, as it may race and users don't have any sane way to pick a slot and hoping it will not be taken. Let the userspace to register a range of fixed file slots in which the auto-allocation happens. The use case is splittting the fixed table in two parts, where on of them is used for auto-allocation and another for slot-specified operations. Signed-off-by:

Put it with the filetable code, which is where it belongs. While doing so, have the helpers take a ctx rather than an io_kiocb. It doesn't make sense to use a request, as it's not an operation on the request itself. It applies to the ring itself. Signed-off-by: -

This also means moving a bit more of the fixed file handling to the filetable side, which makes sense separately too. Signed-off-by: -
