Comment 0 for bug 1911438

CIFS team requested below patch to be backported (it was marked for stable last month) to Ubuntu 18.04.

Patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/cifs/transport.c?id=6988a619f5b79e4efadea6e19dcfe75fbcd350b5
"cifs: allow syscalls to be restarted in __smb_send_rqst()"

Since 6988a619f5b79e4efadea6e19dcfe75fbcd350b5 hasn't been picked up for 5.4.0-1031-azure (the current 18.04 kernel version for Azure image), I would like make a request for backport.

Please let me know, if you have any questions.
