Hi all, with this patch series we try to change the fs freeze behavior in order to sleep in a killable state instead of sleeping in uninterruptible state. The patches are *NOT* tested because but a first review is welcome. The design is simply: 1) Internal fs operations are not changed from fsfreeze point of view, sb_start_intwrite is not changed; 2) sb_start_write and sb_start_pagefault now return a proper error code if the process receive SIGKILL and all the functions must manage this error and return EINTR or VM_FAULT_RETRY. Marco Stornelli (4): fsfreeze: add new internal __sb_start_write_wait fsfreeze: manage kill signal when sb_start_write is called fsfreeze: manage kill signal when sb_start_pagefault is called fsfreeze: avoid to return zero in __get_user_pages fs/btrfs/file.c | 9 +++++++-- fs/btrfs/inode.c | 4 +++- fs/buffer.c | 4 +++- fs/cifs/file.c | 4 +++- fs/ext4/inode.c | 4 +++- fs/ext4/mmp.c | 3 ++- fs/ext4/super.c | 4 +++- fs/f2fs/file.c | 4 +++- fs/fuse/file.c | 4 +++- fs/gfs2/file.c | 4 +++- fs/namespace.c | 8 ++++++-- fs/nilfs2/file.c | 4 +++- fs/ntfs/file.c | 4 +++- fs/ocfs2/file.c | 4 +++- fs/ocfs2/mmap.c | 4 +++- fs/open.c | 8 ++++++-- fs/splice.c | 4 +++- fs/super.c | 47 ++++++++++++++++++++++++++++++++++++++++------- fs/xfs/xfs_file.c | 4 +++- include/linux/fs.h | 19 ++++++++++++------- mm/filemap.c | 11 ++++++++--- mm/filemap_xip.c | 4 +++- mm/memory.c | 2 +- 23 files changed, 127 insertions(+), 40 deletions(-) -- 1.7.3.4 --- -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
