Abstract
A technique manages filesystem blocks of a filesystem. The technique involves modifying an inode structure which identifies a filesystem directory, the directory's inode structure currently including a set of filesystem blocks which was allocated to the directory's inode structure to hold filesystem data. The technique further involves, after modifying the directory's inode structure, performing a directory check operation to determine whether the filesystem directory is empty. The technique further involves reclaiming, from the directory's inode structure, the set of filesystem blocks which was allocated to the directory's inode structure to hold the filesystem data when a result of the directory check operation indicates that the filesystem directory is empty, and not reclaiming the set of filesystem blocks from the directory's inode structure when the result of the directory check operation indicates that the filesystem directory is not empty.
