Subject: [PATCH] fs/ntfs3: Fix memory corruption when page_size changes
The rework in fs/ntfs3: Reduce stack usage
changes log->page_size but doesn't change the associated
log->page_mask and log->page_bits.
That results in the bytes value in read_log_page
getting a negative value, which is bad when it is
passed to memcpy.
The kernel panic can be observed when connecting an
ntfs formatted drive that has previously been connected
to a Windows machine to a Raspberry Pi 5, which by defauilt
uses a 16K kernel pagesize.
