    Subject[PATCH 5.17 1030/1126] gfs2: Fix gfs2_file_buffered_write endless loop workaround
    Date
    From: Andreas Gruenbacher <agruenba@redhat.com>

    commit 46f3e0421ccb5474b5c006b0089b9dfd42534bb6 upstream.

    Since commit 554c577cee95b, gfs2_file_buffered_write() can accidentally
    return a truncated iov_iter, which might confuse callers. Fix that.

    Fixes: 554c577cee95b ("gfs2: Prevent endless loops in gfs2_file_buffered_write")
