отладить путь ввода-вывода файловой системы XFS (debug the I/O path of an XFS filesystem)
Описание (Description)
xfs_io is a debugging tool like xfs_db(8), but is aimed at
examining the regular file I/O paths rather than the raw XFS
volume itself. These code paths include not only the obvious
read/write/mmap interfaces for manipulating files, but also cover
all of the XFS extensions (such as space preallocation,
additional inode flags, etc).
