  "message": "[PATCH] knfsd: reduce stack consumption\n\nA typical nfsd call trace is\n nfsd -\u003e svc_process -\u003e nfsd_dispatch -\u003e nfsd3_proc_write -\u003e\n   nfsd_write -\u003enfsd_vfs_write -\u003e vfs_writev\n\nThese add up to over 300 bytes on the stack.\nLooking at each of these, I see that nfsd_write (which includes\n nfsd_vfs_write) contributes 0x8c to stack usage itself!!\n\nIt turns out this is because it puts a \u0027struct iattr\u0027 on the stack so\nit can kill suid if needed.  The following patch saves about 50 bytes\noff the stack in this call path.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
