Therefore, the real path mount must be kept writable so long as the writable map exists. This may not be strictly needed for ovelrayfs private upper mount, but it is correct to take the mnt_writers count in the vfs helper.

This problem gets masked in practice because most fs.h using sites use rcupreempt.h (and other headers) which includes percpu.h which brings in asm/page.h indirectly. We cannot add asm/page.h to asm/fs.h because page.h is not an exported header. Move simple_transaction_set() to the other simple-transaction file helpers in fs/libfs.c. This removes the include file hell and also reduces kernel size a bit.

When i_size is read or written, i_size_seqcount is read/written as well, so it make sense to group these two fields together in the same cache line. This patch moves i_size_seqcount next to i_size, and also moves i_version to let offsetof(struct inode, i_size) being 0x40 instead of 0x3c (for 32bits platforms). For 64 bits platforms, i_size_seqcount doesnt exist, and the move of a 'long i_version' should not introduce a new hole because of padding.
