  • 83fe27ea5   rcu: Make SRCU optional by using CONFIG_SRCU ... Browse Code »

    SRCU is not necessary to be compiled by default in all cases. For tinification
    efforts not compiling SRCU unless necessary is desirable.

    The current patch tries to make compiling SRCU optional by introducing a new
    Kconfig option CONFIG_SRCU which is selected when any of the components making
    use of SRCU are selected.

    If we do not select CONFIG_SRCU, srcu.o will not be compiled at all.

    829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after

    so the savings are about ~2000 bytes.

  • 80f44b152   quota: Make QUOTACTL config be selected by its users ... Browse Code »

    Remove "depends on" line from QUOTACTL config option and rather select
    the option explicitely from config options which need it. It makes more
    sense this way and also fixes Kconfig warning due to GFS2 selecting
    QUOTACTL but QUOTACTL not depending on it.

  • 62af9b520   quota: Convert __DQUOT_PARANOIA symbol to standard config option ... Browse Code »

    Make __DQUOT_PARANOIA define from the old days a standard config option
    and turn it off by default.

    This gets rid of a quota warning about writes before quota is turned on
    for systems with ext4 root filesystem. Currently there's no way to legally
    solve this because /etc/mtab has to be written before quota is turned on
    on most systems.

  • 498c60153   quota: Implement quota format with 64-bit space and inode limits ... Browse Code »

    So far the maximum quota space limit was 4TB. Apparently this isn't enough
    for Lustre guys anymore. So implement new quota format which raises block
    limits to 2^64 bytes. Also store number of inodes and inode limits in
    64-bit variables as 2^32 files isn't that insanely high anymore.

    The first version of the patch has been developed by Andrew Perepechko
    .

  • 86e931a35   VFS: Export dquot_send_warning ... Browse Code »

    Sending a message to userspace in a generic format to warn
    of events (e.g. quota exceeded) in the quota subsystem is
    a generically useful feature. This patch makes some minor
    changes to the send_message function from dquot.c renaming
    it quota_send_message, moving it to quota.c and exporting it
    for use by filesystems which do not use the dquot code.
