  "message": "GFS2: Add readahead to sequential directory traversal\n\nThis patch adds read-ahead capability to GFS2\u0027s\ndirectory hash table management.  It greatly improves\nperformance for some directory operations.  For example:\nIn one of my file systems that has 1000 directories, each\nof which has 1000 files, time to execute a recursive\nls (time ls -fR /mnt/gfs2 \u003e /dev/null) was reduced\nfrom 2m2.814s on a stock kernel to 0m45.938s.\n\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n",
