[PATCH 3/3] md: reuse sb length-checking logic

The logic in super_1_load() to check the length of the superblock against (new_)data_offset has the same purpose as the newly-created super_1_sb_length_ok(). The latter is also more complete in that it check for overlap between the superblock write and the bitmap. Signed-off-by: Christopher

[PATCH v2 1/3] md: factor out repeated sb alignment logic

super_1_load() and super_1_sync() both contain a copy of logic to pad out the superblock size so that it is aligned on a logical block boundary. Factor into new function, and use round_up() rather than explict bitmask-based calculation. Signed-off-by: Christopher Unkel --- This series replaces

associated performance penalty. Respect the physical block alignment when possible, that is, when the write padded out to the physical block doesn't run into the data or bitmap. Signed-off-by: Christopher Unkel --- This series replaces the first patch of the previous series (https://lkml.org/lkml/
