[GIT PULL for v6.11] vfs pg_error

[Christian Brauner]

Hey Linus,

/* Summary */
This contains work to remove almost all remaining users of PG_error from
filesystems and filesystem helper libraries. An additional patch will be coming
in via the jfs tree which tests the PG_error bit. Afterwards nothing will be
testing it anymore and it's safe to remove all places which set or clear the
PG_error bit. The goal is to fully remove PG_error by the next merge window.

/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)

All patches are based on v6.10-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */

Merge conflicts with mainline
=============================

There's one merge conflict in fs/nsfs/symlink.c
After conflict resolution the function should look like this:

static int nfs_symlink_filler(struct file *file, struct folio *folio)
{
        struct inode *inode = folio->mapping->host;
        int error;

        error = NFS_PROTO(inode)->readlink(inode, &folio->page, 0, PAGE_SIZE);
        folio_end_read(folio, error == 0);
        return error;
}
