  • c8b91accf   clean statfs-like syscalls up ... Browse Code »

    New helpers: user_statfs() and fd_statfs(), taking userland pathname and
    descriptor resp. and filling struct kstatfs. Syscalls of statfs family
    (native, compat and foreign - osf and hpux on alpha and parisc resp.)
    switched to those. Removes some boilerplate code, simplifies cleanup
    on errors...

  • 365b18189   add f_flags to struct statfs(64) ... Browse Code »

    Add a flags field to help glibc implementing statvfs(3) efficiently.

    We copy the flag values from glibc, and add a new ST_VALID flag to
    denote that f_flags is implemented.

  • ebabe9a90   pass a struct path to vfs_statfs ... Browse Code »

    We'll need the path to implement the flags field for statvfs support.
    We do have it available in all callers except:

    - ecryptfs_statfs. This one doesn't actually need vfs_statfs but just
    needs to do a caller to the lower filesystem statfs method.
    - sys_ustat. Add a non-exported statfs_by_dentry helper for it which
    doesn't won't be able to fill out the flags field later on.

    In addition rename the helpers for statfs vs fstatfs to do_*statfs instead
    of the misleading vfs prefix.
