  • 8d57a98cc   block: add secure discard ... Browse Code »

    Secure discard is the same as discard except that all copies of the
    discarded sectors (perhaps created by garbage collection) must also be
    erased.

  • de75d60d5   block: make sure that REQ_* types are seen even with CONFIG_BLOCK=n ... Browse Code »

    These form the basis of the basic WRITE etc primitives, so we
    need them to be always visible. Otherwise we see errors like:

    mm/filemap.c:2164: error: 'REQ_WRITE' undeclared
    fs/read_write.c:362: error: 'REQ_WRITE' undeclared
    fs/splice.c:1108: error: 'REQ_WRITE' undeclared
    fs/aio.c:1496: error: 'REQ_WRITE' undeclared

  • 7cc015811   bio, fs: separate out bio_types.h and define READ/WRITE constants in terms of BIO_RW_* flags ... Browse Code »

    linux/fs.h hard coded READ/WRITE constants which should match BIO_RW_*
    flags. This is fragile and caused breakage during BIO_RW_* flag
    rearrangement. The hardcoding is to avoid include dependency hell.

    Create linux/bio_types.h which contatins definitions for bio data
    structures and flags and include it from bio.h and fs.h, and make fs.h
    define all READ/WRITE related constants in terms of BIO_RW_* flags.
